d35849d0e1 merge GCC 5.3. round 1. this probably won't work :-) 
libsanitizer likely needs to be re-ported, though i've done most of
the updating we'll need i think already.

4d5abbe83f import GCC 5.3.0. see these urls for details which are too large to 
include here:

	http://gcc.gnu.org/gcc-4.9/changes.html
	http://gcc.gnu.org/gcc-5/changes.html

(note that GCC 5.x is a release stream like GCC 4.9.x, 4.8.x, etc.)


the main issues we will have are:

The default mode for C is now -std=gnu11 instead of -std=gnu89.

ARM:
The deprecated option -mwords-little-endian has been removed.
The options -mapcs, -mapcs-frame, -mtpcs-frame and -mtpcs-leaf-frame
 which are only applicable to the old ABI have been deprecated.

MIPS:
The o32 ABI has been modified and extended. The o32 64-bit
 floating-point register support is now obsolete and has been removed.
 It has been replaced by three ABI extensions FPXX, FP64A, and FP64.
 The meaning of the -mfp64 command-line option has changed. It is now
 used to enable the FP64A and FP64 ABI extensions.

93abc59558 protect the entire contents of regsub.c with extern "C". 
this fixes the tools build, at least.

also, remove the no longer needed cdefs.h from one of these copies.

3965f5d7b6 PR/50646: Use the c99 cabs math builtins directly, because cabs and cabsf 
have broken ABI's can cabsl does not exist. The correct(?) probably fix is
to change the cabs builtins to point to the c99 variants directly...

4fe0054f39 Fix logic bug where __cpuid gets called when __get_cpuid_max() returns 0. 
This happens when __level == 0, from libgcc/config/i386/cpuinfo.c#285.

fc89a2852b Use -f with cp. 
When the source tree is 444 (as should be unremarkable), cp results in
object files that are 444, which when cp'd again without -f result in
an error.

23d6404318 Correct temporary directory preference order in libiberty's choose_tmpdir(). 
Because it is intended to be persistent, /var/tmp is about the worst possible
choice for temporary files for most users of libiberty.  /tmp works better,
because the the defined semantics of /tmp allow for a non-persistent tmpfs
to be used.  This should improve performance when /tmp is a tmpfs and it is
difficult or impossible to have an environment variable or command line -pipe
flag passed to every piece of the toolchain.

7593e659ff By changing rs6000_elf_reloc_rw_mask to return 3 if using a powerpc64 ABI 
on NetBSD, we basicly eliminate the only difference between have -fPIC or
not.  This enables us to turn on MKPICLIB for powerpc64.
