e64e72b794 Make several cleanups to Andrews varargs change:
1. Pass Value*'s into lowering methods so that the proper pointers can be
   added to load/stores from the valist
2. Intrinsics that return void should only return a token chain, not a token
   chain/retval pair.
3. Rename LowerVAArgNext -> LowerVAArg, because VANext is long gone.

c6bead211b I really didn't think this was necessary. But, Legalize wasn't running again
and legalizing the extload.  Strange.  Should fix most alpha regressions.

f4b3278aeb 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.

35f0a4f24e iniital checkin of ELFWriter implementation
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 :)

e5eb6f829c Add some simplifications for MULH[SU]. This allows us to compile this:
long %bar(long %X) {
  %Y = mul long %X, 4294967297
  ret long %Y
}

to this:

l1_bar:
        mov %EAX, DWORD PTR [%ESP + 4]
        mov %EDX, %EAX
        add %EDX, DWORD PTR [%ESP + 8]
        ret

instead of:

l1_bar:
        mov %ECX, DWORD PTR [%ESP + 4]
        mov %EDX, 1
        mov %EAX, %ECX
        mul %EDX
        add %EDX, %ECX
        add %EDX, DWORD PTR [%ESP + 8]
        mov %EAX, %ECX
        ret
