There are still another 2 uses of PointerType::getElementType in
Evaluator when evaluating BitCast's on pointers. BitCast's on pointers
should be removed when opaque ptr is ready, so I just keep them as is.

This is a second speculative compile time optimization to address a reported regression. My actual suspicion is that availability of no-self-wrap is making some *other* bit of code trigger, but let's rule this out.
Recently we started generate DBG_VALUEs with $noreg operands.
This crashes SIPostRABundler, and it should not iterate these
registers anyway.

`vector::InsertElementOp` and `vector::ExtractElementOp` have had their `position`
operand changed to accept `AnySignlessIntegerOrIndex` for better operability with
operations that use `index`, such as affine loops.
LLVM's `extractelement` and `insertelement` can also accept `i64`, so lowering
directly to these operations without explicitly inserting casts is allowed. SPIRV's
equivalent ops can also accept `i64`.

This patch resolves many of the failures in the `filesystems/` buckets in the libc++ tests. It adds the correct flag to `fopen` and marks a test case as unsupported. In particular, that test assumes time is stored as a 64 bit value when on MVS it is stored as 32 bit.

The aim of this patch is to resolve the missing `table_size` symbol (see reduced test case). That const variable is declared and defined in //libcxx/include/locale//; however, the test case suggests that the symbol is missing. This is due to a C++ pitfall (highlighted [[ https://quuxplusone.github.io/blog/2020/09/19/value-or-pitfall/ | here ]]). In summary, assigning the reference of `table_size` doesn't enforce the const-ness and expects to find `table_size` in the DLL. The fix is to use `constexpr` or have an out-of-line definition in the src (for consistency).

This implements nearly the same logic as getLocForWriteEx(), and
is only used in one place. In that context, we should also know
that getLocForWriteEx() returns a non-None result. As such,
consolidate everything to use one function.
This patch makes it possible to use the newly added useDefaultAttributePrinterParser and useDefaultTypePrinterParser dialect options without any using namespace declarations. Two things had to be done to make this possible:
* Fully qualify any type usages or functions from the mlir namespace in the generated C++ code
* Makes sure to emit the printers and parsers inside the same namespace as the Dialect

This file was way more complicated than it needed to be.
This patch removes the automagic reference-to-pointer delegation and
replaces the template specializations with regular free functions
(taking reference arguments).
The reason I chose references is twofold:
- there are more arguments being passed by reference than by pointer
- the reference arguments make it more obvious that there is a lot of
leaking going on in there.
Currently, the code was assuming that the pointer arguments have some
kind of a special meaning and that pointer functions take ownership of
their arguments, which isn't true (it's possible it was true at some
point in the past, I haven't done the archeology).
This makes it easier to implement proper lifetime management in
follow-up patches.

This change moves logic which we'd added specifically for less than tests so that it applies to equalities and greater than tests as well. The basic idea is that if we can show an IV cycles infinitely through the same series on self-wrap, and that the exit condition must be taken to prevent UB, we can conclude that it must be taken before self-wrap and thus infer said flag.
The motivation here is simple loops with unsigned induction variables w/non-one steps and inequality tests. A toy example would be:
for (unsigned i = 0; i != N; i += 2) { body; }
If body contains no side effects, and this is a mustprogress function, we can assume that this must be a finite loop and thus that the exit count is N/2.

Returning failure when tile sizes are all zero prevents the change in
the marker. This makes pattern rewriter run the pattern multiple times
only to exit when it hits a limit. Instead just clone the operation
(since tiling is essentially cloning in this case). Then the
transformation filter kicks in to avoid the pattern rewriter to be
invoked many times.

checkOrderedReductions looks for Phi nodes which can be classified as in-order,
meaning they can be vectorised without unsafe math. In order to vectorise the
reduction it should also be classified as in-loop by getReductionOpChain, which
checks that the reduction has two uses.
In this patch, a similar check is added to checkOrderedReductions so that we
now return false if there are more than two uses of the FAdd instruction.
This fixes PR52515.

Compiling code for AMD GPUs requires knowledge of which chipset is
being targeted, especially if the code uses chipset-specific
intrinsics (which is the case in a downstream convolution generator).
This commit adds `target`, `chipset` and `features` arguments to the
SerializeToHsaco constructor to enable passing in this required
information.
It also amends the ROCm integration tests to pass in the target
chipset, which is set to the chipset of the first GPU on the system
executing the tests.

The libgcc runtime library provides __register_frame and
__deregister_frame functions, which can be used by dynamic code
generators to register an .eh_frame section, which contains one or
more Call Frame Information records, each consisting of a Common
Information Entry record followed by one or more Frame Description
Entry records. This libunwind library also provides __register_frame
and __deregister_frame functions, but they are aliases for
__unw_add_dynamic_fde and __unw_remove_dynamic_fde and thus can only
take a single FDE.
This patch adds __unw_add_dynamic_eh_frame_section and
__unw_remove_dynamic_eh_frame_section functions which explicitly use
the .eh_frame format. Clients such as the ORCv2 platform and runtime
can check for these functions and use them if unwinding is being
provided by libunwind, or fall back to __register_frame and
__deregister_frame if unwinding is provided by libgcc.
