[mir-strip-debug] Fix debug location info strip for bundled instructions (#113676)
Fix bug that `mir-strip-debug` pass does not remove debug location from
bundled instructions.
Problem arises during testing that debug info does not affect
optimization passes output (`llvm-lit` with ` -Dllc="llc
-debugify-and-strip-all-safe"`), when pass operates on MIR with bundled
instructions + memory operands.
Let mir test check looks like:
```
CHECK-NEXT: BUNDLE {
CHECK-NEXT: $r3 = LD $r1, $r2 :: (load (s64) from %ir.a, !tbaa !2)
CHECK-NEXT: }
```
So as `mir-strip-debug` pass does not process bundled instructions,
running `llc -debugify-and-strip-all-safe` on the test will produce the
following output:
```
BUNDLE {
$r3 = LD $r1, $r2, debug-location !DILocation(line: 3, column: 1, scope: <0x608cb2b99b10>) :: (load (s64) from %ir.a, !tbaa !2)
}
```
And test will fail, but it shouldn't.
Seems like the root cause is that `mir-strip-debug` pass should remove
debug location from bundled instructions.

Don't accidentally create MachineFunctions in mir-debugify/mir-strip-debugify
We should only modify existing ones. Previously, we were creating
MachineFunctions for externally-available functions. AFAICT this was benign
in tree but ultimately led to asan bugs in our out of tree target.

[Debugify] Strip added metadata in the -debugify-each pipeline
Summary:
Share logic to strip debugify metadata between the IR and MIR level
debugify passes. This makes it simpler to hunt for bugs by diffing IR
with vs. without -debugify-each turned on.
As a drive-by, fix an issue causing CallGraphNodes to become invalid
when a dead llvm.dbg.value prototype is deleted.

Add -debugify-and-strip-all to add debug info before a pass and remove it after
Summary:
This allows us to test each backend pass under the presence
of debug info using pre-existing tests. The tests should not
fail as a result of this so long as it's true that debug info
does not affect CodeGen.
In practice, a few tests are sensitive to this:
* Tests that check the pass structure (e.g. O0-pipeline.ll)
* Tests that check --debug output. Specifically instruction
dumps containing MMO's (e.g. prelegalizercombiner-extends.ll)
* Tests that contain debugify metadata as mir-strip-debug will
remove it (e.g. fastisel-debugvalue-undef.ll)
* Tests with partial debug info (e.g.
patchable-function-entry-empty.mir had debug info but no
!llvm.dbg.cu)
* Tests that check optimization remarks overly strictly (e.g.
prologue-epilogue-remarks.mir)
* Tests that would inject the pass in an unsafe region (e.g.
seqpairspill.mir would inject between register alloc and
virt reg rewriter)
In all cases, the checks can either be updated or
--debugify-and-strip-all-safe=0 can be used to avoid being
affected by something like llvm-lit -Dllc='llc --debugify-and-strip-all-safe'
I tested this without the lost debug locations verifier to
confirm that AArch64 behaviour is unaffected (with the fixes
in this patch) and with it to confirm it finds the problems
without the additional RUN lines we had before.

Add pass to strip debug info from MIR
Summary:
Removes:
* All LLVM-IR level debug info using StripDebugInfo()
* All debugify metadata
* 'Debug Info Version' module flag
* All (valid*) DEBUG_VALUE MachineInstrs
* All DebugLocs from MachineInstrs
This is a more complete solution than the previous MIRPrinter
option that just causes it to neglect to print debug-locations.
* The qualifier 'valid' is used here because AArch64 emits
an invalid one and tests depend on it
