[SimplifyCFG] Do not thread branches into uncontrolled convergent regions
SimplifyCFG's foldCondBranchOnValueKnownInPredecessor can thread an edge past
a block that acts as a reconvergence point. If the threaded destination reaches
an uncontrolled convergent operation before returning to the threaded-through
block, the transform can change which dynamic instance of the convergent
operation is executed.
Add a conservative destination scan for this fold and skip the threading
candidate when it can reach an uncontrolled convergent call before returning
to the original block. Controlled convergent operations using convergence
control tokens are left alone.
Fixes ROCM-26496.

nfs_clstate.c: Fix CB_RECALL handling for NFSv4.1/4.2
Recent testing with a modified NFSv4.1/4.2 client that
sometimes ignored CB_RECALL callbacks, identified a few
problems when handling the unusual case of CB_RECALL not
be performed by the client.
- The csa_cachethis argument to CB_SEQUENCE was being ignored.
- The CB_SEQUENCE operation would reply NFSERR_DELAY
after the first CB_RECALL attempt, making retries
ineffective.
- The code could return NFSERR_RESOURCE, which is a
NFSv4.0 specific error code.
This patch fixes the above three problems.
The patch only affects the NFSv4.1/4.2 client when
delegations are being issued and the client somehow
fails to handle a CB_RECALL callback of a delegation,
which is an unusual case.

[Clang] Fix APSInt width of template argument in FinishCXXExpansionStmt() (#208859)
After merging #169680, we started getting assertions in
IntegerLiteral::Create() on some ARM systems:
```
Assertion `V.getBitWidth() == C.getIntWidth(type) &&
"Integer type is not the correct size for constant."'
```
The expansion statements patch doesn't ever create an IntegerLiteral
directly, but there is one place where we create a TemplateArgument of
type 'ptrdiff_t', but we unconditionally set the bit width of its APSInt
to 64 bits.
Presumably, the assertion is due to 'ptrdiff_t' not being a 64-bit type
on these systems, so make sure that we query its bit width and use that
as the width of the APSInt.
