gcc: Fix optimization bug.
GCC-PR rtl-optimization/34628
* combine.c (try_combine): Stop and undo after the first combination
if an autoincrement side-effect on the first insn has effectively
been lost.
In libc++'s type_traits header, avoid warnings (activated by our use of
-Wsystem-headers) about potential keyword compatibility problems, by
adding a __libcpp prefix to the applicable identifiers.
Upstream is still debating about this, but we need it now, to be able to
import clang 3.4.
gcc: merge small upstream changes.

* reload1.c (merge_assigned_reloads) : Do not merge a RELOAD_OTHER
instruction with a RELOAD_FOR_OPERAND_ADDRESS instruction.

X86: cvtpi2ps is just an SSE instruction with MMX operands. It has no AVX
equivalent.
Give it the right register format so we can also emit it when AVX is enabled.

gcc: Bring updates from Google's enhanced gcc-4.2.1.
Google released and enhanced version of gcc-4.2.1 plus their local
patches for Android[1].
The patches are owned by Google and the license hasn't been changed
from the original GPLv2. We are only bringing a subset of the
available patches that may be helpful in FreeBSD, in other words,
changes specific to android are not included.

gcc: Fix postreload-gcse treatment of call-clobbered registers.
gcc: Record some previous commits in the ChangeLog.gcc43 file.
Fix a segfault / internal compiler error.
Among other causes, when gcc throws a warning before parsing any tokens,
the cur_token pointer is at the beginning of malloc'd memory.
Dereferencing cur_token[-1] can cause a segfault.
Code taken from OpenBSD
http://www.openbsd.org/cgi-bin/cvsweb/src/gnu/gcc/libcpp/errors.c
which was a more complete fix than the one I originally coded.
Use correct casts in gcc's emmintrin.h for the first arguments of the
following builtin functions:
* __builtin_ia32_pslldi128() takes __v4si instead of __v8hi
* __builtin_ia32_psllqi128() takes __v2di instead of __v8hi
* __builtin_ia32_psradi128() takes __v4si instead of __v8hi
This should fix the following errors when building the LINT kernel with
gcc:
sys/crypto/aesni/aesni_wrap.c:191: error: incompatible type for argument 1 of
'__builtin_ia32_psradi128'
sys/crypto/aesni/aesni_wrap.c:195: error: incompatible type for argument 1 of
'__builtin_ia32_pslldi128'

Sync with NetBSD. The functional change is to make the output when
comparing a directory to an mtree file more compatible with fmtree when
FreeBSD 9 compatiblity mode is on. This output is clearly intended for
humans not computers, but some tools such as mergemaster's -U option rely
on it.

Pull in r191896 from upstream llvm trunk:
CaptureTracking: Plug a loophole in the "too many uses" heuristic.
The heuristic was added to avoid spending too much compile time in a
specially crafted test case (PR17461, PR16474) with many uses on a
select or bitcast instruction can still trigger the slow case. Add a
check for that case.
This only affects compile time, don't have a good way to test it.
This fixes the excessive compile time spent on a specific file of the
graphics/rawtherapee port.

Otherwise, a formatted string with a strlen equal to the remaining
buffer space would have the last character omitted (because vsnprintf
always null-terminates), and later the assert in backtrace_symbols_fmt
would fail.

Upgrade to the latest version of mtree from NetBSD. This revision
re-removes the printing of size for non-regular files, supports

be processed as /etc/group entries.
Includes one trivial portability fix (including <stdint.h> in three
files) that has been committed upstream.
