Bill Wendling 3f6bb2713e Add a flag to indicate that an instruction is as cheap (or cheaper) than a move ...

instruction to execute. This can be used for transformations (like two-address
conversion) to remat an instruction instead of generating a "move"
instruction. The idea is to decrease the live ranges and register pressure and
all that jazz.
