[DirectX] Remove unused heap resources (#218093)
Add handling of `llvm.dx.resource.handlefromheap` to
`DXILRemoveUnusedResources` pass. In practice heap resources are usually
assigned to local variables, and get cleaned up in earlier passes if
unused. If that does not happen for some reason, they get removed by
`DXILRemoveUnusedResources`.

[MLIR] Add inherent attribute visitor (#217881)
Visit inherent attributes directly from operation property storage.
Allow visitors to replace values through generated property conversions.
Keep populateInherentAttrs as a wrapper and migrate core IR callers.
This is intended as a more efficient than populateInherentAttrs that
avoids materializing the list.

[CIR] Diagnose a union whose spanning member supplies no data
The accept rule and mapCIRType disagreed on what counts as data. The rule
asked !memberIsEmptyRecord, the mapper asked holdsDataForABI, and the two
part ways on an access unit holding only unnamed bit-fields: the rule
counted it, the mapper dropped it. So a union could be accepted on the
strength of a member the classifier never saw, and one holding a 3-bit
named field beside a 64-bit unnamed one came out i8 where classic gives
i64, with no diagnostic.
Ask both questions of the same member so the two agree. A union holding a
20-bit named field beside a 64-bit unnamed one goes NYI as well, and that
one is correct today at i64, so this costs a little coverage until the
unnamed unit can carry its bytes into the classification.

[Object][Wasm] Add more error checking to handling of COMMON symbols (#218557)
* Check for valid alignment when parsing common symbols (also for data
symbols)

* Add support for COMMON in YAML emitter for tests
[CIR][OpenCL] Preserve OpenCL source languages in CIR (#217846)
Represent OpenCL C and C++ for OpenCL source languages in CIR module
attributes. Emit the source language from CIRGen so later lowering can
distinguish OpenCL language modes without reconstructing them from
target metadata.

[libc] Add stub for confstr (#218789)
POSIX defines confstr as returning strings for various macros (see:
https://pubs.opengroup.org/onlinepubs/9799919799/functions/confstr.html)
This PR adds an implementation as experimental that always returns that
there's no valid string.

[MLIR][Math] Enable strict property assembly format (#217275)
Enable the strict properties assembly format mode for the Math dialect.
Spell the classification fast-math attribute in the declarative format

[MLIR][Affine] Reject fully consumed bounded delinearize split (#217472)
Do not apply SplitDelinearizeSpanningLastLinearizeArg when the split
would consume an entire outer-bounded basis. Rewriting that case can
discard earlier linearization inputs and previously built an invalid
zero-result prefix operation.

[MLIR][ODS] Print prop-dict fields with custom printers (#217589)
Generate a key-value prop-dict printer that dispatches each field to its
ODS printer while retaining attribute conversion for non-compositional
default parsers.
Keep operation-specific property printer hooks ahead of the generated
implementation and preserve legacy input compatibility.

[ORC] Remove lookupAndRecordAddrs (#218671)
All uses of lookupAndRecordAddrs have been replaced by lookupAndApply,

Add conduct email contact for the CODE_OF_CONDUCT page (#218787)
This turns out to be the landing page users get linked to when
(temporarily or permanently) banned. And since there is no way to
privately message through GitHub, this is basically where they end up
and having an immediate way to reach the CoC Committee to discuss those
moderation actions is important.

[CIR] Rewrap the x86_64 classifier bridge comment
This paragraph lost its shape over a couple of merges and ended up with
a short orphaned line in the middle. Rewrapping the whole block lets
classifyX86_64Function land mid-line so the lines fill evenly. The
wording is untouched, only the line breaks moved.
