Summary:
This patch addresses https://bugs.llvm.org/show_bug.cgi?id=46256
The spec of coroutine requires that the expression co_await promise.final_suspend() shall not be potentially-throwing.
To check this, we recursively look at every call (including Call, MemberCall, OperatorCall and Constructor) in all code
generated by the final suspend, and ensure that the callees are declared with noexcept. We also look at any returned data
type that requires explicit destruction, and check their destructors for noexcept.
This patch does not check declarations with dependent types yet, which will be done in future patches.
Updated all tests to add noexcept to the required functions, and added a dedicated test for this patch.
This patch might start to cause existing codebase fail to compile because most people may not have been strict in tagging
all the related functions noexcept.

Add option to filter which op the OpDefinitionsGen run on. This enables having multiple ops together in the same TD file but generating different CC files for them (useful if one wants to use multiclasses or split out 1 dialect into multiple different libraries). There is probably more general query here (e.g., split out all ops that don't have a verify method, or that are commutative) but filtering based on op name (e.g., test.a_op) seemed a reasonable start and didn't require inventing a query specification mechanism here.

Summary: Previous code would try to verify DW_AT_ranges and if any ranges would overlap, it would stop attributing any ranges after this to the DIE which caused incorrect errors to be reported that a DIE's address ranges were not contained in the parent DIE's ranges. Added a fix and a test.

This reverts 057c9c7ee0
This was orignally done so we could separate the compatibility
values and the llvm internal only features into a separate entries
in the feature array. This was needed when we explicitly had to
convert the feature into the proper 32-bit chunk at every reference
and we didn't want things moving around.
Now everything is in an array and we have helper funtions or macros
to convert encoding to index. So we renumbering is no longer an
issue.
Treat function result like dummy argument: a SAVE statement without an
entity-list does not make it saved.

Currently, in order to extract an element from a bf16 vector, we cast
the vector to an i16 vector, perform the extraction, and cast the result to
bfloat. This behavior was copied from the old fp16 implementation.
The goal of this patch is to achieve optimal code generation for lane
copying intrinsics in a subsequent patch (LLVM fails to fold certain
combinations of bitcast, insertelement, extractelement and
shufflevector instructions leading to the generation of suboptimal code).

Prevent fixes being displayed if usages are found in the scratch buffer.
See [[ https://bugs.llvm.org/show_bug.cgi?id=46219 | Fix-It hints are being generated in the ScratchBuffer ]].
It may be wise down the line to put in a general fix in clang-tidy to prevent ScratchBuffer replacements being applied, but for now this will help.

Add a new builtin-function __builtin_expect_with_probability and
intrinsic llvm.expect.with.probability.
The interface is __builtin_expect_with_probability(long expr, long
expected, double probability).
It is mainly the same as __builtin_expect besides one more argument
indicating the probability of expression equal to expected value. The
probability should be a constant floating-point expression and be in
range [0.0, 1.0] inclusive.
It is similar to builtin-expect-with-probability function in GCC
built-in functions.

Add a way to quit the interactive script interpreter from a shell tests.
Currently, the only way (that I know) to exit the interactive Lua
interpreter is to send a EOF with CTRL-D. I noticed that the embedded
Python script interpreter accepts quit (while the regular python
interpreter doesn't). I've added a special case to the Lua interpreter
to do the same.

Currently we stop exploring candidates too early in some cases.
In particular, we can continue checking the defining accesses of
non-removable MemoryDefs and defs without analyzable write location
(read clobbers are already ruled out using MemorySSA at this point).
This features matches ELFAsmParser and makes it possible to use `.section ".llvm.call-graph-profile","n"`

Summary:
Currently when --passes is used, any passes specified via -foo are
ignored. Explicitly bail out when that happens.
This requires changing some tests. Most were straightforward, but
codegenprepare-produced-address-math.ll is tricky. One of its RUNs runs
CodeGenPrepare. I tried porting CodeGenPrepare to the NPM, but ended up
getting stuck when I needed a TargetMachine. NPM doesn't have support
for MachineFunctions yet. So I just deleted that RUN line, since it was
mass-added in https://reviews.llvm.org/D54848 and is likely not that
useful.

This adds the abstract converter interface. The abstract converter is an

Summary:
Currently, the TableGen rewrite generates redundant native calls in MLIR DRR files. This is a problem as some native calls may involve significant computations (e.g. when performing constant propagation where every values in a large tensor is touched).
The pattern was as follow:
```c++
if (native-call(args)) tblgen_attrs.emplace_back(rewriter, attribute, native-call(args))
```
The replacement pattern compute `native-call(args)` once and then use it both in the `if` condition and the `emplace_back` call.

Following on from this RFC[0] from a while back, this is the first patch towards
implementing variadic debug values.
This patch specifically adds a set of functions to MachineInstr for performing
operations specific to debug values, and replacing uses of the more general
functions where appropriate. The most prevalent of these is replacing
getOperand(0) with getDebugOperand(0) for debug-value-specific code, as the
operands corresponding to values will no longer be at index 0, but index 2 and
upwards: getDebugOperand(x) == getOperand(x+2). Similar replacements have been
added for the other operands, along with some helper functions to replace
oft-repeated code and operate on a variable number of value operands.

Summary:
Windows forbidden file path characters are used in a field `file`, while creating a dump `dot` file using an argument -analyzer-dump-egraph. It specifically relates to angle brackets when using `<scratch space>`, `<built-in>`, `<command line>` values in filenames. It causes that script exploded-graph-rewriter.py incorrectly parses the dump.
Fix:
Remove forbidden characters from filename for Windows platform, when creating graph dump file.

This patch extends the AccessChainOp index type handling to be able to deal with
all Integer type indices (i.e., all bit-widths and signedness symantics).
There were two ways of achieving this:
1- Backward compatible: The new way of handling the indices will assume that
an index type is i32 by default if not specified in the assembly format,
this way all the old tests would pass correctly.
2- Enforce the format: This unifies the spv.AccessChain Op format and all the old
tests had to be updated to reflect this change or else they fail.
I picked option-2 to unify the Op format and avoid having optional index-type fields
that can lead to somewhat confusing tests format and multiple representations for
the same Op with undocumented assumption that an index is i32 unless stated.
Nonetheless, reverting to option-1 should be straightforward if preferred or needed.

These operations do member-wise versions of the all of the listed
operations. This patch implements all of the binaryoperators for these
types. Note that the test is required to use codegen as I could not come
up with a good way to validate the values without the array-subscript
operator implemented (which is likely a much more involved change).

Summary:
As discussed previously when landing patch for OpenMP in Flang, the idea is
to share common part of the OpenMP declaration between the different Frontend.
While doing this it was thought that moving to tablegen instead of Macros will also
give a cleaner and more powerful way of generating these declaration.
This first part of a future series of patches is setting up the base .td file for
DirectiveLanguage as well as the OpenMP version of it. The base file is meant to
be used by other directive language such as OpenACC.
In this first patch, the Directive and Clause enums are generated with tablegen
instead of the macros on OMPConstants.h. The next pacth will extend this
to other enum and move the Flang frontend to use it.

Before this patch, we use `(uint32_t)AbbrCode - (uint32_t)FirstAbbrCode` to index the abbreviation. It's impossible for we to use the preceeding abbreviation of the previous one (e.g., if the previous DIE's `AbbrCode` is 2, we are unable to use the abbreviation with index 1). In this patch, we use `AbbrCode` to index the abbreviation directly.
