f9317bf0be Fix tied operands in phi-coalescing.mir test; try to adapt MLRegalloc tests 
Fix a test using invalid MLIR using different VRegs for the tied operands
of ADD64rr, which happened to trigger an assertion after my latest
changes.

Also attempting to adjust the MLRegalloc tests to the adjusted regalloc
(though I don't have a 100% working setup for them even without my
changes)

5b26f4f042 Reland "[MLGO] ML Regalloc Priority Advisor" 
This relands commit 8f4f26ba5bd04f7b335836021e5e63b4236c0305, which was reverted in 91c96a806cae58539e40c9e443a08bde91ccc91e because of Buildbot failures. The previous model test is not compatible with tflite. e.g. https://lab.llvm.org/buildbot/#/builders/6/builds/14041

8f4f26ba5b [MLGO] ML Regalloc Priority Advisor 
The bulk of the implementation is common between 'release' mode (==AOT-ed
model) and 'development' mode (for training), the main difference is
that in development mode, we may also log features (for training logs),
inject scoring information and then produce the log file.
