LSRA throughput tweaks (#11698)

Convert LinearScan::getVarReg() to take a tracked var index, not varNum

Change LSRA to create Intervals only for tracked variables

Change getIntervalForLocalVar() to take a tracked variable index.

Create getIntervalForLocalVarNode()

This reduces instruction count of superpmi replay over minopts tests by 0.6%.
