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.

7273339dc4 Eliminate EARLY_BUILD flag. It is redundant and means MK_CLANG_FULL=no
and MK_LLDB=no, so set those explicitly (now that we can do
that). Simplify tests for these variables as well, since we know they
will always be defined regardless of the phase of the build.

54ff5d7323 Add a SUBDIR_PARALLEL option to bsd.subdir.mk, to allow make to process
all the SUBDIR entries in parallel, instead of serially.  Apply this
option to a selected number of Makefiles, which can greatly speed up the
build on multi-core machines, when using make -j.

This can be extended to more Makefiles later on, whenever they are
verified to work correctly with parallel building.

I tested this on a 24-core machine, with make -j48 buildworld (N = 6):

                before    stddev       after    stddev
                =======   ======       =======  ======
real time        1741.1     16.5         959.8     2.7
user time       12468.7     16.4       14393.0    16.8
sys  time        1825.0     54.8        2110.6    22.8

(user+sys)/real     8.2                   17.1

E.g. the build was approximately 45% faster in real time.  On machines
with less cores, or with lower -j settings, the speedup will not be as
impressive.  But at least you can now almost max out a machine with
buildworld!

f785676f2a Upgrade our copy of llvm/clang to 3.4 release. This version supports
all of the features in the current working draft of the upcoming C++
standard, provisionally named C++1y.

The code generator's performance is greatly increased, and the loop
auto-vectorizer is now enabled at -Os and -O2 in addition to -O3.  The
PowerPC backend has made several major improvements to code generation
quality and compile time, and the X86, SPARC, ARM32, Aarch64 and SystemZ
backends have all seen major feature work.

df5d2454a3 Pull in r170135 from upstream clang trunk:
Dont use/link ARCMT, StaticAnalyzer and Rewriter to clang when the user
  specifies not to. Dont build ASTMatchers with Rewriter disabled and
  StaticAnalyzer when it's disabled.

  Without all those three, the clang binary shrinks (x86_64) from ~36MB
  to ~32MB (unstripped).

To disable these clang components, and get a smaller clang binary built
and installed, set WITHOUT_CLANG_FULL in src.conf(5).  During the
initial stages of buildworld, those extra components are already
disabled automatically, to save some build time.

This commit merges the latest LLVM sources from the vendor space. It
also updates the build glue to match the new sources. Clang's version
number is changed to match LLVM's, which means /usr/include/clang/2.0
