7b60e03d - Reland "CodeGen][NewPM] Port MachineScheduler to NPM. (#125703)" (#126684)

Reland "CodeGen][NewPM] Port MachineScheduler to NPM. (#125703)" (#126684) `RegisterClassInfo` was supposed to be kept alive between pass runs, which wasn't being done leading to recomputations increasing the compile time. Now the Impl class is a member of the legacy and new passes so that it is not reconstructed on every pass run. --------- Co-authored-by: Christudasan Devadasan <christudasan.devadasan@amd.com>
