[WebAssembly] Fold sign-extending shifts into signed loads in FastISel (#185906)
WebAssembly FastISel currently fails to fold sign-extension patterns
composed of zero-extending loads followed by shift operations. This
results in redundant shift and constant instructions in the output.
Before:
i32.load8_u $push3=, 0($0)
i32.const $push0=, 24
i32.shl $push1=, $pop3, $pop0
i32.const $push4=, 24
i32.shr_s $push2=, $pop1, $pop4
The matched shift instruction sequence is removed and safely folded into
a single sign-extending load, erasing the dead code via the
MachineBasicBlock iterator.
After:
i32.load8_s $push0=, 0($0)
Fixed: #184302
[NVPTX][AutoUpgrade] atom.load intrinsics should be autoupgraded to monotonic atomicrmw for NVPTX (#187140)
Prior to https://github.com/llvm/llvm-project/pull/179553, the seq_cst
qualifier was being ignored. The expected codegen for these intrinsics
is `atom.relaxed`- which corresponds to `Monotonic`. The fix does to
AutoUpgrade what https://github.com/llvm/llvm-project/pull/185822 does
to clang.

[LV] Replace remaining LogicalAnd to vp.merge in EVL optimization. (#184068)
This patch replace the remaining LogicalAnd to vp.merge in the second
pass to not break the `m_RemoveMask` pattern in the optimizeMaskToEVL.
This can help to remove header mask for FindLast reduction (CSA) loops.

[CIR] Add handling for nounwind attributes (#187096)
This adds support for setting the `nounwind` attribute on declarations
and call sites in CIR.
Currently, we have both `nothrow` and `nounwind` in CIR. I've chosen to
use `nothrow` in this PR because it was the most common. I plan to
combine them, using `nounwind` everywhere since that's the LLVM IR
spelling, but that's a more invasive so I'd like to defer it to a future
change.

[lldb][Module] Don't try to locate scripting resources without a ScriptInterpreter (#187091)
I'm in the process of moving `SanitizedScriptingModuleName` into
`ScriptInterpreter` as a `virtual` API. The nullptr check inside the
constructor made that more difficult because it implied we may not have
a `ScriptInterpreter` available to call the sanitization API on. Really
the `nullptr` check is redundant because even if we succesfully sanitize
and then locate some scripts, `Module::LoadScriptingResourceInTarget`
bails out if we don't have a `ScriptInterpreter`.
This patch moves the early exit in `LoadScriptingResourceInTarget` to
before we make the call to `LocateExecutableScriptingResources`. That
way we ensure we never get to `SanitizedScriptingModuleName` without a
valid `ScriptInterpreter`.

[IR2Vec] Remove redundant death test for invalid TypeID (#187143)
The `NumericIDMapInvalidInputs` test has two `EXPECT_DEATH` calls for
invalid `Type::TypeID` values. The second value (`MaxTypeIDs + 10`) is
redundant: `getIndex` has a one-sided assert, so any value greater or
equal to `MaxTypeIDs` takes the same code path as the value already
tested by the first call.
The test began failing after
https://github.com/llvm/llvm-project/pull/186888, which introduced
`ByteTyID`. The value of `MaxTypeIDs + 10` became 32, which falls
outside the representable range of the `enum`, making the cast UB. To
avoid accidentally triggering this test when adding new types, it should
probably be removed.
[mlir][spirv] Add comparison and elementwise ternary ops in TOSA Ext Inst Set (#186356)
This patch introduces the following comparison and elementwise ternary

spirv.Tosa.Equal
spirv.Tosa.Greater
spirv.Tosa.GreaterEqual
Also dialect and serialization round-trip tests have been added.
