[mlir] provide Python bindings for the Transform dialect
Python bindings for extensions of the Transform dialect are defined in separate
Python source files that can be imported on-demand, i.e., that are not imported
with the "main" transform dialect. This requires a minor addition to the
ODS-based bindings generator. This approach is consistent with the current

such projects can include their custom extensions into the bundle similarly to

[mlir] add VectorizeOp to structured transform ops
Vectorization is a key transformation to achieve high performance on most
architectures. In the transform dialect, vectorization is implemented as a
parameterizable transform op. It currently applies to a scope of payload IR
delimited by some isolated-from-above op, mainly because several enabling
transformations (such as affine simplification) are needed to perform
vectorization and these transformation would apply to ops other than the "main"
computational payload op. A separate "navigation" transform op that obtains the
isolated-from-above ancestor of an op is introduced in the core transform
dialect. Even though it is currently only useful for vectorization,
isolated-from-above ops are a common anchor for transformations (usually
implemented as passes) that is likely to be reused in the future.

[GVN] Enable enable-split-backedge-in-load-pre option by default
This option was added in D89854. It prevents GVN from performing
load PRE in a loop, if doing so would require critical edge
splitting on the backedge. From the review:
> I know that GVN Load PRE negatively impacts peeling,
> loop predication, so the passes expecting that latch has
> a conditional branch.
In the PhaseOrdering test in this patch, splitting the backedge
negatively affects vectorization: After critical edge splitting,
the loop gets rotated, effectively peeling off the first loop
iteration. The effect is that the first element is handled
separately, then the bulk of the elements use a vectorized
reduction (but using unaligned, off-by-one memory accesses) and
then a tail of 15 elements is handled separately again.
It's probably worth noting that the loop load PRE from D99926 is
not affected by this change (as it does not need backedge
splitting). This is about normal load PRE that happens to occur
inside a loop.

[libclang] Fall back to getMainExecutable when dladdr fails
musl-libc doesn't support dladdr in statically linked binaries:
> Are you using static or dynamic linking? If static, dladdr is just a
> stub that always fails. It could be implemented to work under some
> conditions, but it would be highly dependent on what options you
> compile the binary with, since by default static binaries do not
> contain the bloat that would be needed to perform introspection.
Source: https://www.openwall.com/lists/musl/2013/01/15/25 (in response
to a bug report).
Libclang unfortunately uses dladdr to find the ResourcesPath so will
fail if it is linked statically on Alpine Linux. This patch fixes this
issue by falling back to getMainExecutable if dladdr returns an error.

Increase the default maximum stack walk
lldb will only backtrace a fixed number of stack frames, as a
last-ditch attempt to avoid a runaway looping backtrace. It's
unusual that anyone ends up depending on this final safety net in
years. I picked the original number of 300000 was picked by seeing
how many stack frames I could make in a small recursive function
on Darwin systems before using the default stack space. Checking
again today on a modern system, I can exceed this limit & lldb will
not show the original invocation of the recursing call. Double the
old value to cover this larger maximum possible stack frame count,

[flang] Make extension explicit: exponent-letter matching kind-param
As an extension for REAL literals, we allow an exponent letter which
matches an explicit kind-param. The standard requires the exponent
to be 'E' if a kind-param is present. This patch
- documents this extension in Extensions.md
- enables a portability warning if it is used with -pedantic
The test case for this, kinds05.f90, needs D125804, which makes
test_errors.py test warnings as well, to actually test the warnings.
I include it already now to keep things together, it will do no harm
(I hope ...).
We also add WARNING-directives to the test kinds04.f90 in preparation
for D125804. As the exponent-letter 'Q' does not imply the same kind
on all platforms, the emitted warnings are platform-dependent.
Therefore, the test is duplicated into two variants which are run
conditionally.
Finally, we promote the portability warning for when the exponent letter
is neither 'E' nor matching the kind-param to a standard warning.

[flang] Avoid spurious warnings from reading module files
When processing the literal constants of the various kinds of
INTEGER that are too large by 1 (e.g., 2147483648_4) in expression
analysis, emit a portability warning rather than a fatal error if
the literal constant appears as the operand to a unary minus, since
the folded result will be in range. And don't emit any warning if
the negated literal is coming from a module file -- f18 wrote the
module file and the warning would simply be confusing, especially to
the programmer that wrote (-2147483647_4-1) in the first place.
Further, emit portability warnings for the canonical expressions for
infinities and NaN (-1./0., 0./0., & 1./0.), but not when they appear
in a module file, for the same reason. The Fortran language has no
syntax for these special values so we have to emit expressions that
fold to them.
