[llvm-mca] Improved support for dependency-breaking instructions.
The tool assumes that a zero-latency instruction that doesn't consume hardware
resources is an optimizable dependency-breaking instruction. That means, it
doesn't have to wait on register input operands, and it doesn't consume any
physical register. The PRF knows how to optimize it at register renaming stage.
