[InstrRef] Fix mismatch between LiveDebugValues and salvageCopySSA (llvm#124233)

The LiveDebugValues pass and the instruction selector (which calls
salvageCopySSA) need to be consistent on what they consider a copy
instruction. With llvm#75184, the
definition of what a copy instruction is was narrowed for AArch64 to
exclude a w->x ORR and treat it as a zero-extend rather than a copy

However, to make sure LiveDebugValues still treats a w->x ORR as a copy,
the new function, isCopyLikeInstr was created. We need to make sure that
salvageCopySSA also calls that function.

This patch addresses this mismatch.
