Although cmake should be platform-independent, we've observed
that some aspects of Python detection don't work on all platforms,
even with recent versions of cmake. This appears to be due to bugs
in the python detection logic, especially when the NumPy component
is required and not located within the python installation.
As a workaround, this patch first searches for "Development" before
searching for "Development.Module", which seems to workaround the
issue.

The pass can currently not handle to_memref(to_tensor(x)) folding where a cast is necessary. This is required with the new unified bufferization. There is already a canonicalization pattern that handles such foldings and it should be used during this pass.

These transformations already operate on memref operations (as part of
splitting up the standard dialect). Now that the operations have moved,
it's time for these transformations to move as well.

We already convert to BitVector internally, and other APIs (namely Operation::eraseOperands)
already use BitVector as well. Switching over provides a common format between

The option parser currently does not properly handle nested options, meaning that
in some cases we can print pass pipelines that we can't actually parse back in. For example,
from #52885 we currently can't parse in inliner pipelines that have nested pipeline strings.
This commit adds handling for string values (e.g. "...") and nested options
(e.g. `foo{baz{bar=10 pizza=11}}`).

This diff modifies the tablegen specification and code generation for
BitEnumAttr attributes in MLIR Operation Definition Specification (ODS) files.
Specifically:
- there is a new tablegen class for "none" values (i.e. no bits set)
- single-bit enum cases are specified via bit index (i.e. [0, 31]) instead of
the resulting enum integer value
- there is a new tablegen class to represent a "grouped" bitwise OR of other
enum values
This diff is intended as an initial step towards improving "fastmath"
optimization support in MLIR, to allow more precise control of whether certain
floating point optimizations are applied in MLIR passes. "Fast" math options
for floating point MLIR operations would (following subsequent RFC and
discussion) be specified by using the improved enum bit support in this diff.
For example, a "fast" enum value would act as an alias for a group of other
cases (e.g. finite-math-only, no-signed-zeros, etc.), in a way that is similar
to support in C/C++ compilers (clang, gcc).

This is part of splitting up the standard dialect. The move makes sense anyways,
given that the memref dialect already holds memref.atomic_rmw which is the non-region
sibling operation of std.generic_atomic_rmw (the relationship is even more clear given
they have nearly the same description % how they represent the inner computation).

The GPU dialect currently contains an explicit reference to LLVMFuncOp
during verification to handle the situation where the kernel has already been
converted. This commit changes that reference to instead use FunctionOpInterface,
which has two main benefits:
* It allows for removing an otherwise unnecessary dependency on the LLVM dialect
* It removes hardcoded assumptions about the lowering path and use of the GPU dialect
