986e05bc2a Completely revamp the way llvm, clang and lldb are built.
* Bootstrap llvm-tblgen and clang-tblgen with a minimal llvm static
  library, that has no other dependencies.
* Roll up all separate llvm libraries into one big static libllvm.
* Similar for all separate clang and lldb static libraries.
* For all these libraries, generate their .inc files only once.
* Link all llvm tools (including extra) against the big libllvm.
* Link clang and clang-format against the big libllvm and libclang.
* Link lldb against the big libllvm, libclang and liblldb.

N.B.: This is work in progress, some details may still be missing.

It also heavily depends on bsd.*.mk's support for SRCS and DPSRCS with
relative pathnames, which apparently does not always work as expected.
For building llvm, clang and lldb though, it seems to work just fine.

The main idea behind this restructuring is maintainability and build
peformance.  The previous large number of very small libraries, each
with their own generated files and dependencies was slow to traverse
and hard to understand.

Possible future improvements:
* Only build certain targets, e.g. for most regular users having just
  one target will be fine.  This will shave off some build time.
* Building the big llvm, clang and lldb libraries as shared (private)
  libraries.
* Adding other components from the LLVM project, such as lld.

6ca8079c85 Pull in r265122 from upstream llvm trunk (by James Molloy):
Fix for pr24346: arm asm label calculation error in sub

  Some ARM instructions encode 32-bit immediates as a 8-bit integer
  (0-255) and a 4-bit rotation (0-30, even) in its least significant 12
  bits. The original fixup, FK_Data_4, patches the instruction by the
  value bit-to-bit, regardless of the encoding. For example, assuming
  the label L1 and L2 are 0x0 and 0x104 respectively, the following
  instruction:

    add r0, r0, #(L2 - L1) ; expects 0x104, i.e., 260

  would be assembled to the following, which adds 1 to r0, instead of
  260:

    e2800104 add r0, r0, #4, 2 ; equivalently 1

  The new fixup kind fixup_arm_mod_imm takes care of the encoding:

    e2800f41 add r0, r0, #260

  Patch by Ting-Yuan Huang!

This fixes label calculation for ARM assembly, and is needed to enable
ARM assembly sources for OpenSSL.

c371433e4a For clang, move the definition of FREEBSD_CC_VERSION into its own header
file, lib/clang/freebsd_cc_version.h, instead of reusing Version.inc.
The header is only included from one .cpp file in the clang tree.

This minimizes the number of .cpp files that need to be rebuilt if the
version is bumped.

b5e99283f4 Pull in r271548 from upstream llvm trunk (by me):
Only attempt to detect AVG if SSE2 is available

  Summary:
  In PR29973 Sanjay Patel reported an assertion failure when a certain
  loop was optimized, for a target without SSE2 support.  It turned out
  this was because of the AVG pattern detection introduced in rL253952.

  Prevent the assertion failure by bailing out early in
  `detectAVGPattern()`, if the target does not support SSE2.

  Also add a minimized test case.

  Reviewers: congh, eli.friedman, spatel

  Subscribers: emaste, llvm-commits

  Differential Revision: http://reviews.llvm.org/D20905

This should fix assertion failures ("Requires at least SSE2!") when
building the games/0ad port with CPUTYPE=pentium3.

06a6cbdf5f Add FREEBSD_CC_VERSION which will be used to define __FreeBSD_cc_version.
The WITH_SYSTEM_COMPILER build option will rely on this value to determine what
__FreeBSD_cc_version the source tree will produce.  This value will be compared
against the /usr/bin/cc value to determine if a new compiler is needed.

Start with 1100002 which is 1 more than than the value we've had since
3.8.0 to ensure that all changes since then are present.

c43c22982e Limit Options.inc generation to desired targets
As mentioned in the Makefile there's an "atrocious" hack to generate a
different version of Options.inc.h, depending on the library being
built.

Remove the catch-all else case and limit it to specific libraries, so
that we don't accidentally use the Options.inc.h from clangdriver if a
future libary also uses Options.inc.h.

6a5ac7dc11 Use the new bmake .dinclude feature to make these safe.
At least FAST_DEPEND won't even run 'make depend', so the code was
potentially broken with FAST_DEPEND anyhow.  The .dinclude directive
will ignore missing files rather than make them be fatal.

b9cd412e7b FAST_DEPEND: Always run depend via beforebuild which removes many hacks.
This will generate dependencies rather than depending on the previous behavior
of depending on the guessed OBJS: *.h dependecies or a user running
'make depend'.

Experimentation showed that depending only on headers was not enough and
prone to .ORDER errors.  Downstream users may also have added
dependencies into beforedepend or afterdepend targets.  The safest way to
ensure dependencies are generated before build is to run 'make depend'
beforehand rather than just depending on DPSRCS+SRCS.

Note that the OBJS_DEPEND_GUESS mechanism (a.k.a .if !exists(.depend) then
foo.o: *.h) is still useful as it improves incremental builds with missing
.depend.* files and allows 'make foo.o' to usually work, while this
'beforebuild: depend' ensures that the build will always find all dependencies.
The 'make foo.o' case has no means of a 'beforebuild' hook.

This also removes several hacks in the DIRDEPS_BUILD:
- NO_INSTALL_INCLUDES is no longer needed as it mostly was to work around
  .ORDER problems with building the needed headers early.
- DIRDEPS_BUILD: It is no longer necesarry to track "local dependencies" in
  Makefile.depend.

  These were only in Makefile.depend for 'clean builds' since nothing would
  generate the files due to skipping 'make depend' and early dependency
  bugs that have been fixed, such as adding headers into SRCS for the
  OBJS_DEPEND_GUESS mechanism.  Normally if a .depend file does not exist then
  a dependency is added by bsd.lib.mk/bsd.prog.mk from OBJS: *.h.  However,
  meta.autodep.mk creates a .depend file from created meta files and inserts
  that into Makefile.depend.  It also only tracks *.[ch] files though which can
  miss some dependencies that are hooked into 'make depend'.  This .depend
  that is created then breaks incremental builds due to the !exists(.depend)
  checks for OBJS_DEPEND_GUESS.  The goal was to skip 'make depend' yet it only
  really works the first time.  After that files are not generated as expected,
  which r288966 tried to address but was using buildfiles: rather than
  beforebuild: and was reverted in r291725.  As noted previously,
  depending only on headers in beforebuild: would create .ORDER errors
  in some cases.

  meta.autodep.mk is still used to generate Makefile.depend though via:
    gendirdeps: Makefile.depend
    .END: gendirdeps

  This commit allows removing all of the "local dependencies" in
  Makefile.depend which cuts down on churn and removes some of the
  arch-dependent Makefile.depend files.

  The "local dependencies" were also problematic for bootstrapping.
