[DebugInfo] Remove getPrevNonDebugInstruction (#148859)

With the advent of intrinsic-less debug-info, we no longer need to
scatter calls to getPrevNonDebugInstruction around the codebase. Remove
most of them -- there are one or two that have the "SkipPseudoOp" flag
turned on, however they don't seem to be in positions where skipping
anything would be reasonable.
