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.

make AliasAnalysis know that VAArg writes memory.  This is extremely conservative and should be fixed

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
