43f6afd7ee Update the ARMv6 core clang targets to be an arm1176jzf-s. This brings us
in line with gcc in base as this makes llvm generate code for the armv6k
variant of the instruction set.

7abc3b4099 Remove unused readline header

Fix a bug in xmmintrin.h.

  The last step of _mm_cvtps_pi16 should use _mm_packs_pi32, which is a function
  that reads two __m64 values and packs four 32-bit values into four 16-bit
  values.

9f6783a973 Merge -fstandalone-debug from Clang r198655:
Implement a new -fstandalone-debug option. rdar://problem/15685848
  It controls everything that -flimit-debug-info used to, plus the
  vtable type optimization. The old -fno-limit-debug-info option is now an
  alias to -fstandalone-debug and vice versa.

  Standalone is the default on Darwin until dtrace is updated to work with
  non-standalone debug info (rdar://problem/15758808).

  Note: I kept the LimitedDebugInfo name in CodeGenOptions::DebugInfoKind
  because NoStandaloneDebugInfo sounded even more confusing.

all FreeBSD versions, not just 10.x and earlier.  Apparently too many

f1587c2296 lldb: Invoke PT_KILL from ProcessPosix::DoDestroy
We previously sent SIGKILL to the debuggee in DoDestroy, but did not
actually detach or kill via ptrace.  It seems that this somehow didn't
matter on Linux, but did on FreeBSD.

This would happen when quitting LLDB while stopped at a breakpoint, for
example.  The debuggee remained stopped in ptrace (with the signal
either pending or lost).  After a timeout of a second or two LLDB exits,
which caused the debuggee to resume and dump core from an unhandled
SIGTRAP.

BringProcessIntoLimbo is a poorly named wrapper for ptrace(PT_KILL)
which is the desired behaviour from DoDestroy.

Moreover, if libc++ is used, the libstdc++ include directories should
not be in the search path at all.  These directories are now only used
if you pass -stdlib=libstdc++.

a8b6bed223 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.

  In the following code:

  the array 'arr' is represented as a variable size array in the template.
  If 'A::sz' gets value below in the translation unit, the array in
  instantiation can turn into constant size array.

1df952388b On platforms where clang is the default compiler, don't build gcc or libstdc++.
To enable them, set WITH_GCC and WITH_GNUCXX in src.conf.
Make clang default to using libc++ on FreeBSD 10.
Bumped __FreeBSD_version for the change.

GCC is still enabled on PC98, because the PC98 bootloader requires GCC to build
(or, at least, hard-codes the use of gcc into its build).

Thanks to everyone who helped make the ports tree ready for this (and bapt
for coordinating them all).  Also to imp for reviewing this and working on the
forward-porting of the changes in our gcc so that we're getting to a much
better place with regard to external toolchains.
