First draft of X86 LLC backend. This should be OK for small programs like
...
Shootout, but it has some issues with bigger programs. Work in progress.

For 16 and 32-bit multiplies, use the IMUL instruction instead of the MUL instruction.
...
This allows us to not force the use of the EAX/AX registers!

Rename many instructions to their Intel asm-compatible names. This
...
involves removing the [bwl] suffixes from instruction names, as well
as some other distinguishing marks (32/64/80 on fp insns, _i suffixes, etc.)
Lowercase all instr. names as well for consistency's sake.

Don't print < > around names. The assembler can't take it.
Print pseudoinstructions only as comments. The poor little assembler can't
take that, either.

Special case simple binary operator X op C
...
This avoid generating a register to hold C, which in turn speeds up the
register allocator by a lot: ~9% on 164.gzip and ~17% on 256.bzip2. This
also speeds up other passes. This also speeds up execution of the program
marginally, and makes the asm much easier to read. :)
