3a9e7690ba 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.

8f413fa9c0 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.

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.

3f55c24df9 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.

548abfcbd6 Implement support for the bizarre 3DNow! encoding (which is unlike anything
else in X86), and add support for pavgusb.  This is apparently the
only instruction (other than movsx) that is preventing ffmpeg from building
with clang.

If someone else is interested in banging out the rest of the 3DNow! 
instructions, it should be quite easy now.

ec45f60cab Major changes to Cortex-A9 itinerary.
1. Model dual issues as two FUs.
2. Model the pipelines correctly: two symmetric ALUs, the multiplier is a
   dependent pipeline on ALU0.
The changes do not have much impact on codegen right now. But I plan to make
pre-RA scheduler multi-issue aware which should take good advantage of the
changes.

d476914607 fix a regression introduced in r115243, in which the instruction
backing int_x86_ssse3_pshuf_w got removed.  This caused PR8280.
