[DDG][NFC] Colorize DDG dot graph (#181618)
All blocks and edges are currently colored black which makes it
difficult to distinguish while looking at huge graph.
This simple patch implements the following colorization to make it
visually more distinguishable.
1. Pi-blocks - styled to rounded, filled, light-yellow fill, dark orange
border
2. Multi-instruction blocks - Light cyan fill
3. MemoryDependence edges are now colored red.
4. Register def-use edges are now colored blue.
This patch implements `getNodeAttributes()` to return the string of
attributes to apply to the node.
[RISCV] Remove VMConstraint from VAESKF1_VI/VAESKF2_VI. (#181887)
These instructions don't have a VM operand. If these instructions use a
V0 destination, the VMConstraint code calls getReg() on the the last
operand which is an immediate. This triggers an assertion. Not sure
what happens on a release build. It probably treats the immediate as a
value in the RISCV register info enum.
[clang][deps] Ensure the service outlives async module compiles (#181772)
This PR fixes a race condition discovered by thread sanitizer in the
asynchronous dependency scanner implementaion.
The implementation assumed that whenever a new thread is spawned to
compile a module, the primary scanning thread must wait for it to finish
to read the PCM it produces. This is not true - it's possible for the
implicit build on the primary thread to decide to compile the same
module too, leaving the asynchronous thread running without any kind of
synchronization. This means the TU scan may return, the service may get
destroyed, but the asynchronous thread continues running with the VFS
caches and module cache implementation destroyed, leading to crashes.
This PR fixes this by awaiting all asynchronous threads at the end of a
TU scan.
[VPlan] Remove VPDerivedIVRecipe and VPScalarIVStepsRecipe from VPHeaderPHIRecipe doc comment. NFC (#181862)
These aren't subclasses of VPHeaderPHIRecipe, I'm not sure if the class
hierarchy changed or not.
Also add the other subclasses to the list.

[ProfCheck][Matrix] Add profile data where relevant
This patch tackles two cases:
1. Checks around aliasing/overlapping ranges. This is runtime dependent
on the pointer values passed in, which we have no way of knowing
without additional profiling.
2. Loop backedges. For these we also have an associated trip count, so
we set up the branch weights to represent this.
Tests updated/profcheck-xfail.txt updated.

[NFC][Matrix] Make CreateLoop take ConstantInt for Bound/Step
These should always be constants (unless someday we add support for
scalable matrices and then we can revisit). Explicitly pass them as
ConstantInt so we can avoid needing to downcast in a future PR that will
calculate appropriate branch weights using these values.

[ProfCheck][Matrix] Propagate profile information for selects
LowerMatrixIntrinsics creates new selects in the process of lowering
matrix intrinsics. The condition of such selects remains the same as
before. Because of this, we can directly propagate the profile
information for all selects on scalar conditions.
