[AArch64][GISel] Clamp bitcast to v2i64 (#191360)
This helps to not lower, improving the number of nodes that we expand
into and improving the quality of the generated code.

[OpenACC] Fix pattern API check failures in acc-loop-tiling pass (#188968)
Two bugs were introduced/revealed by
MLIR_ENABLE_EXPENSIVE_PATTERN_API_CHECKS:
1. `ACCLoopTilingImpl::matchAndRewrite` returned `success()` for loops
with no tile values, triggering "pattern returned success but IR did not
change". Fixed by returning `failure()` instead.
2. `moveOpsAndReplaceIVs` moved ops between blocks via `splice()` and
updated operands via `replaceAllUsesInRegionWith()` without notifying
the rewriter. This caused "operation fingerprint changed" errors since
the moved ops' parent op and operands changed without
`startOpModification`/ `finalizeOpModification`. Fixed by wrapping all
moved ops (and their nested ops) with rewriter modification
notifications.

[MLIR][MemRef] Fix DimOfReifyRankedShapedTypeOpInterface IR-change on failure (#188973)
DimOfReifyRankedShapedTypeOpInterface::matchAndRewrite called
reifyDimOfResult via the PatternRewriter. Some implementations delegate
to the coarse-grained reifyResultShapes, which creates ops for ALL
dimensions (e.g. a tensor.dim) before discovering that a specific
dimension is not reifiable (signalled by an empty OpFoldResult).
The pattern then returned failure() once it saw the empty OpFoldResult,
but the newly created ops were already in the IR. Under
MLIR_ENABLE_EXPENSIVE_PATTERN_API_CHECKS this triggered "pattern
returned failure but IR did change".
Fix: record the op immediately before the matched dim op, so we can
identify ops inserted during the reification attempt. If reification
returns an empty (unreifiable) OpFoldResult, erase those newly created
ops before returning failure, restoring the IR to its original state.

deskutils/freeplane: Set JAVA_VERSION
Freeplane fails to start with the current JAVA_DEFAULT (25) with
the error message:
ERROR: Found /usr/local/bin/java in $PATH.
ERROR: It has version 25.0.2
ERROR: Currently, freeplane requires java version 8 or from 11 to 23
ERROR:
ERROR: Select a supported java version
ERROR: by setting FREEPLANE_JAVA_HOME to a valid java location
ERROR: OR use an unsupported java version
ERROR: by setting FREEPLANE_USE_UNSUPPORTED_JAVA_VERSION to 1
So set JAVA_VERSION to a list of supported JDK.
Note that if you start freeplane with the environment variable
FREEPLANE_USE_UNSUPPORTED_JAVA_VERSION=1, then the program fails with
the error message:
