[ReachingDefAnalysis][NFC] Use at instead of lookup for DenseMap access
`at` has an assert that the key exists. Since we are assuming the key exists,
use `at` instead of `lookup`.

Reapply "Convert many LivePhysRegs uses to LiveRegUnits" (#84338)
This only converts the instances where all that is needed is to change
the variable type name.
Basically, anything that involves a function that LiveRegUnits does not
directly have was skipped to play it safe.

through MCRegUnitIterators. This also replaces calls to

[ARM] Attempt to make Tail predication / RDA more resilient to empty blocks
There are a number of places in RDA where we assume the block will not
be empty. This isn't necessarily true for tail predicated loops where we
have removed instructions. This attempt to make the pass more resilient
to empty blocks, not casting pointers to machine instructions where they
would be invalid.
The test contains a case that was previously failing, but recently been
hidden on trunk. It contains an empty block to begin with to show a
similar error.
