[LLVMdev] asm parser functionality

[reed kotler]

It seems that some parts of asm parser should be moved earlier into llvm.

It should be possible to parse inline assembler and produce a list of 
machine instructions that can be merged into the normal instructions of 
a basic block.

This would make many other things be simple to do later.

This guessing about and adjusting for uncertainty in later code when 
inline assembler is present is for the birds.
