Aiden Grossman 8d77f8fde7 [MLGO] Add per-instruction MBB frequencies to regalloc dev features ...

This commit adds in two new features to the ML regalloc eviction
analysis that can be used in ML models, a vector of MBB frequencies and
a vector of indicies mapping instructions to their corresponding basic
blocks. This will allow for further experimentation with per-instruction
features and give a lot more flexibility for future experimentation over
how we're extracting MBB frequency data currently.
