46dafc2fb9 Move the include of MachineLocation.h into MachineModuleInfo.h 
because it declares a std::vector<MachineMove>, and strict
concept checking requires the definition of MachineMove to be
available.

cb8b4e9dd4 - Add target lowering hooks that specify which setcc conditions are illegal, 
i.e. conditions that cannot be checked with a single instruction. For example,
SETONE and SETUEQ on x86.
- Teach legalizer to implement *illegal* setcc as a and / or of a number of
legal setcc nodes. For now, only implement FP conditions. e.g. SETONE is
implemented as SETO & SETNE, SETUEQ is SETUO | SETEQ.
- Move x86 target over.

c070ffc493 FastISel support for exception-handling constructs. 
- Move the EH landing-pad code and adjust it so that it works
   with FastISel as well as with SDISel.
 - Add FastISel support for @llvm.eh.exception and
   @llvm.eh.selector.

the same pattern as roundpd/roundps, the Intel compiler

016196513e Build system tweaks to make it more convenient for the plugin authors. 
Plugins can be now compiled in with a slight Makefile change.

make TOOLNAME=ccc2 BUILTIN_PLUGINS=Clang

1c97db4090 "The original bug was a complaint that _mm_srli_si128 mis-compiled when passed 
a constant vector ("{0x123, 0x456}" syntax).  The fix is to simplify the
_mm_srli_si128 macro, and  move the "* 8" from the macro into the compiler
back-end.  I can't change the existing __builtins because so many people are
using them :-(."
