Philip Reames 15000255d1 [Tests] Remove deopt operands from SafepointIRVerfier tests
This linter has nothing to do with deopt, and the operands had clearly been copied blindly from another source.  Rather than migrate to deopt operand bundle, let's just simplify the tests.

Philip Reames 27304b1737 [Tests] Switch a few statepoint tests to using operand bundles
We've started (D80598) the process of migrating away from the inline operand lists in statepoints to using explicit operand bundles.  Update a few tests to reflect the new preference.  More to come, these were simply the ones outside any obvious grouping.

Arthur Eubanks 922fa2fce3 Run Coverage pass before other *San passes under new pass manager, round 2
Summary:
This was attempted once before in https://reviews.llvm.org/D79698, but
was reverted due to the coverage pass running in the wrong part of the
pipeline. This commit puts it in the same place as the other sanitizers.

This changes PassBuilder.OptimizerLastEPCallbacks to work on a
ModulePassManager instead of a FunctionPassManager. That is because
SanitizerCoverage cannot (easily) be split into a module pass and a
function pass like some of the other sanitizers since in its current
implementation it conditionally inserts module constructors based on
whether or not it successfully modified functions.

This fixes compiler-rt/test/msan/coverage-levels.cpp under the new pass
manager (last check-msan test).

Vedant Kumar d11155d273 [LiveDebugValues] Add cutoffs to avoid pathological behavior
Summary:
We received a report of LiveDebugValues consuming 25GB+ of RAM when
compiling code generated by Unity's IL2CPP scripting backend.

There's an initial 5GB spike due to repeatedly copying cached lists of
MachineBasicBlocks within the UserValueScopes members of VarLocs.

But the larger scaling issue arises due to the fact that prior to range
extension, there are 81K basic blocks and 156K DBG_VALUEs: given enough
memory, LiveDebugValues would insert 101 million MIs (I counted this by
incrementing a counter inside of VarLoc::BuildDbgValue).

It seems like LiveDebugValues would have to be rearchitected to support
this kind of input (we'd need some new represntation for DBG_VALUEs that
get inserted into ~every block via flushPendingLocs). OTOH, large globs
of auto-generated code are typically not debugged interactively.

So: add cutoffs to disable range extension when the input is too big. I
chose the cutoffs experimentally, erring on the conservative side. When
compiling a large collection of Apple software, range extension never
got disabled.

Vedant Kumar 4855534d10 [MachineVerifier] Verify that a DBG_VALUE has a debug location
Summary:
Verify that each DBG_VALUE has a debug location. This is required by
LiveDebugValues, and perhaps by other late passes.

There's an exception for tests: lots of tests use a two-operand form of
DBG_VALUE for convenience. There's no reason to prevent that.

This is an extension of D80665, but there's no dependency.

Philip Reames a0d2fd4a1f [Statepoint] Sink actual_args and gc_args to GCStatepointInst [NFC]
These are the two operand sets which are expected to survive more than another week or so.  Instead of bothering to update the deopt and gc-transition operands, we'll just wait until those are removed and delete the code.

For those following along, this is likely to be the last (major) change in this sequence for about a week.  I want to wait until all of this has been merged downstream to ensure I haven't introduced any bugs (and migrate some downstream code to the new interfaces).  Once that's done, we should be able to delete Statepoint/ImmutableStatepoint without too much work.

MaheshRavishankar 2b0c8546ac [mlir][Linalg] Add pass to remove unit-extent dims from tensor
operands of Generic ops.

Unit-extent dimensions are typically used for achieving broadcasting
behavior. The pattern added (along with canonicalization patterns
added previously) removes the use of unit-extent dimensions, and
instead uses a more canonical representation of the computation.  This
new pattern is not added as a canonicalization for now since it
entails adding additional reshape operations. A pass is added to
exercise these patterns, along with an API entry to populate a
patterns list with these patterns.

Philip Reames 587fa99cfd Default to generating statepoints with deopt and gc-transition bundles if needed
Continues from D80598.

The key point of the change is to default to using operand bundles instead of the inline length prefix argument lists for statepoint nodes. An important subtlety to note is that the presence of a bundle has semantic meaning, even if it is empty. As such, we need to make a somewhat deeper change to the interface than is first obvious.

Existing code treats statepoint deopt arguments and the deopt bundle operands differently during inlining. The former is ignored (resulting in caller state being dropped), the later is merged.

We can't preserve the old behaviour for calls with deopt fed to RS4GC and then inlining, but we can avoid the no-deopt case changing. At least in internal testing, that seem to be the important one. (I'd argue the "stop merging after RS4GC" behaviour for the former was always "unexpected", but that the behaviour for non-deopt calls actually make sense.)
