[PATCH] D138515: [CodeGen][RegAllocFast] Map PhysReg to its current VirtReg

[Christudasan Devadasan via Phabricator via llvm-commits]

This should replace the patch D134951 <https://reviews.llvm.org/D134951> which used the delegate method for a specific purpose.
This is a more generic approach for targets to help identify the exact live range (virtual register) a physical register was currently assigned for. 
While the allocation is in progress, this would serve the purpose of mapping a physical register to its virtual register.
