Fixes GCC libstdc++/29286
The fix seems to work for amd64 but causes segfaults on powerpc.
At this time gcc is much more important on powerpc than on amd64.

This should not happen and just indicates some configuration error which

GCC 4.2 and previous have always warned about
"No newline at end of file".
Upstream GCC removed the warning completely but
Apple made it an optional warning. Adopt it for
compatibility with older GCC and clang.
While here, add comment to complement r258712.

The stdtime sources were moved from lib/libc to contrib/tzcode, and tzfile.h
is not an installed header, so the man page refers to its location in the
source tree.
The documentation could be more clear about the internal nature of the
header, but those changes should go through upstream tzcode.

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:

CodeGen: Don't emit linkage on thunks that aren't emitted because they're
vararg.
This can happen when we're trying to emit a thunk with available_externally
linkage with optimization enabled but bail because it doesn't make sense for
vararg functions.

Move the body of GCCInstallationDetector ctor into an init() function
and call it from its only user. The linux toolchain. This saves quite
a lot of directory searching on other platforms.
See http://docs.freebsd.org/cgi/mid.cgi?51E6FAF5.3080802 for the
original discussion. With this fix, the search for gcc installations is
completely eliminated on FreeBSD.

On FreeBSD lldb sometimes reloads the the main module's (executable's)
symbols at the wrong address. Work around this for now by explicitly
reloading at base_address=0 when it happens.
A proper fix is needed but early testers have reported this issue so
this workaround should allow them to make further progress.

location for the native amd64 ABI. This fixes unwinding over the
signal frame after trampoline was moved to the shared page.
The code would be more correct if using sysctl for the target process
instead of inspecting gdb' own trampoline, but the current change is
least intrusive and currently, we always initialize the native ABI
sysvec first, which means that trampoline location for FreeBSD/amd64
ABI is relatively stable.
Similar change will benefit libunwind.

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.

gcc: Move conditions before an assert.
It is a bit cleaner to check the conditions before calling the assertion.
It also preserves the style from the rest of the code.
This is just a cosmetical change to match better what both Apple's gcc42
and Android's gcc-4.2.1 do.
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. Changes specific
to android are not included.
