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.
4. Now that we have Value*'s available in the lowering methods, pass them
into any load/stores from the valist that are emitted

is at least overloading the right virtual methods. The implementations
are currently wrong though. This fixes Ptrdist/bc, but not other programs
(e.g. siod).

The optimization for locally used allocas was not safe for allocas that
were read before they were written. This change disables that optimization
in that case.

is a mismatch in their character type pointers (i.e. fprintf() prints an
array of ubytes while fwrite() takes an array of sbytes).
We can probably do better than this (such as casting the ubyte to an
sbyte).

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.

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 :)
