Rafael Espindola b1d0789357 Implement a simple alias case and refactor the code a bit so that the 
isInSymtab and isLocal logic in the two loops don't get easily out of sync.

Owen Anderson d8d1dcc09a Use a more efficient lowering of uint64_t --> float that can take advantage of hardware signed integer conversion without 
having to do a double cast (uint64_t --> double --> float).  This is based on the algorithm from compiler_rt's __floatundisf
for X86-64.

Rafael Espindola bce26a1ee0 On ELF we need to know which symbols are used in relocations to decide if 
they should be in the symbol table or not. Instead of "guessing", just compute
the symbol table after the relocations are known.

Jim Grosbach a85a4e21c9 Re-apply r115363 and r115366 now that r115525 has removed the un-needed header 
that caused the circular dependencies on Linux.

Built OK for me on OSX and Linux (Ubuntu) with configure/make and CMake. Will
keep an eye on the bots....

Make sure it restores local variable N1, which corresponds to the condition operand if it fails to match.

This apparently breaks TCE but since that backend isn't in the tree I don't have a test for it.

Bill Wendling 402e54822b The pshufw instruction came about in MMX2 when SSE was introduced. Don't place 
it in with the SSSE3 instructions.

Steward! Could you place this chair by the aft sun deck? I'm trying to get away
from the Astors. They are such boors!

Kevin Enderby a68d004d88 Incorporate suggestions by Daniel Dunbar after his review. Thanks Daniel! 
1) Changed ValidateDwarfFileNumber() to isValidDwarfFileNumber() to be better
   named.  Since it is just a predicate and isn't actually changing any state.

2) Added a missing return in the comments for setCurrentDwarfLoc() in 
   include/llvm/MC/MCContext.h for fix formatting.

3) Changed clearDwarfLocSeen() to ClearDwarfLocSeen() since it does change
   state.

4) Simplified the last test in isValidDwarfFileNumber() to just a one line
   boolean test of MCDwarfFiles[FileNumber] != 0 for the final return statement.
