f805a7c25c Revert r144611 and r144613. 
These tests are actually correct, clang was miscompiling ExeDepsFix::processUses.

Evan fixed the miscompilation in r144628.

3c84ec070a Allow for depencendy-breaking instructions before cvt*. 
This should unbreak clang-x86_64-darwin10-RA, but I can't actually
reproduce the failure.

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.
