Adapt the code for handling uint -> fp conversion for the 32 bit case to
...
handling it in the 64 bit case. The two code paths should probably be merged.

...
is to use RA, which assumes the called function uses RA for the register
holding the return address when it issues a ret.

Initial set of .td file changes necessary to get scalar fp in xmm registers
...
working. The instruction selector changes will hopefully be coming later
this week once they are debugged. This is necessary to support the darwin
x86 FP model, and is recommended by intel as the replacement for x87. As
a bonus, the register allocator knows how to deal with these registers
across basic blocks, unliky the FP stackifier. This leads to significantly
better codegen in several cases.

Add support to the X86 backend for emitting ELF files. To use this, we
...
currently use: llc t.bc --filetype=obj
This will produce a t.o file which is dumpable with readelf. Currently
the file produced is empty, but the scaffolding to do more is now in place.
