Don't generate line&scope debug info for meta-instructions.
MachineInstructions that don't generate any code (such as
IMPLICIT_DEFs) should not generate any debug info either.
Fixes PR33107.
https://bugs.llvm.org/show_bug.cgi?id=33107
This reapplies r303566 without any modifications. The stage2 build
failures persisted even after reverting this patch, and looking back
through history, it looks like these tests are flaky.
