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.

Namely, output the rellocation flags explicitly when loading constants.
Added benifit: save a load when loading from the constant pool.

who said we had to use the return address in the return address register.  Might save a move in many cases

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.

For now, the elf writer is only capable of emitting an empty elf file, with
a section table and a section table string table.  This will be enhanced
in the future :)

should be able to handle this case.  The code is there, so let's see
if it works.

prevent GCSE from forwarding stores to loads around vaarg.  This is uggly, and I am trying to fix the AliasInfo, as it should catch the problem instead.

so this doesn't crash when run.  It is hard to tell if things are right enough to work correctly with all the TmpInstructions running around
