Rafael Espindola 419b6d7ce4 Make ARM and X86 LowerMEMCPY identical by moving the isThumb check into getMaxInlineSizeThreshold
and by restructuring the X86 version.

New I just have to move this to a common place :-)

Rafael Espindola 063f177300 Make ARM an X86 memcpy expansion more similar to each other.
Now both subtarget define getMaxInlineSizeThreshold and the expansion uses it.

Anton Korobeynikov 383a324735 Long live the exception handling!
This patch fills the last necessary bits to enable exceptions
handling in LLVM. Currently only on x86-32/linux.

In fact, this patch adds necessary intrinsics (and their lowering) which
represent really weird target-specific gcc builtins used inside unwinder.

After corresponding llvm-gcc patch will land (easy) exceptions should be
more or less workable. However, exceptions handling support should not be 
thought as 'finished': I expect many small and not so small glitches
everywhere.
