01d79ff86d 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.

54f6032dae - Fixed name mangling conditions to handle 'linkonce' linkage type. In
particular, name mangling for GlobalValues only occurs when the linkage type is
internal or when the name must be mangled to avoid a collision.  See comments in
CWriter::getValueName for more information.

- 'inline' keyword is now emitted for functions with 'linkonce' linkage type.

- Fixed typos.

e99f4cf4ac It seems likely that floats would need a cast too, because they are
ordinarily promoted to doubles.

99c91e021a Do not mark ALL terminators live if any instruciton in the block is live. We only
want to mark it live if it is an unconditional branch.  This fixes bug:
ADCE/2002-05-28-Crash.ll and makes this pass _much_ more useful.

96b07e54dd 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.

Print pseudoinstructions only as comments. The poor little assembler can't
take that, either.
