[clang-format][NFC] Clean up SortIncludesTest.cpp
Wherever applicable, replace EXPECT_EQ with verifyFormat and std::string
with StringRef. Also, change a raw string literal to a regular one.
[AMDGPU] Use LSH for lowering ctlz_zero_undef.i8/i16 (#88512)
Use LSH to lower ctlz_zero_undef instead of subtracting leading zeros
for i8 and i16.
Related to [77615](https://github.com/llvm/llvm-project/pull/77615).

[mlir][intrange] Use `nsw`,`nuw` flags in inference
This patch includes the "no signed wrap" and "no unsigned wrap" flags,
which can be used to annotate some Ops in the `arith` dialect and also
in LLVMIR, in the integer range inference.
The general approach is to use saturating arithmetic operations to infer
bounds which are assumed to not wrap and use overflowing arithmetic
operations in the normal case. If overflow is detected in the normal case,
special handling makes sure that we don't underestimate the result range.
[mlir][intrange] Represent bounds of `ReflectBoundsOp` as `si`/`ui`
This patch adapts the `test.reflect_bounds` test Op to use explicitly
signed and unsigned representation for signed and unsigned bounds of
`IntegerType`s.
This is mostly a cosmetic change as the internal representation of the
ranges is unchanged. However, it improves readability of tests.
Example:
```mlir
// old:
test.reflect_bounds {smax = 127 : i8, smin = -128 : i8, umax = -56 : i8, umin = 100 : i8}
// new:
test.reflect_bounds {smax = 127 : si8, smin = -128 : si8, umax = 200 : ui8, umin = 100 : ui8}
```
[Clang][HLSL] Add environment parameter to availability attribute (#89809)
Add `environment` parameter to Clang availability attribute. The allowed
values for this parameter are a subset of values allowed in the
`llvm::Triple` environment component. If the `environment` parameters is
present, the declared availability attribute applies only to targets
with the same platform and environment.
This new parameter will be initially used for annotating HLSL functions
for the `shadermodel` platform because in HLSL built-in function
availability can depend not just on the shader model version (mapped to
`llvm::Triple::OSType`) but also on the target shader stage (mapped to
`llvm::Triple::EnvironmentType`). See example in #89802 and
microsoft/hlsl-specs#204 for more details.
The environment parameter is currently supported only for HLSL.
Fixes #89802
[CodeGen][SDAG] Skip preferred extend at O0 (#92643)
This is a pure optimization to avoid redundant extensions, but iterating
over all users is expensive, so don't do this at -O0.
[Clang][CodeGen] Start migrating away from assuming the Default AS is 0 (#88182)
At the moment, Clang is rather liberal in assuming that 0 (and by extension unqualified) is always a safe default. This does not work for targets that actually use a different value for the default / generic AS (for example, the SPIRV that obtains from HIPSPV or SYCL). This patch is a first, fairly safe step towards trying to clear things up by querying a modules' default AS from the target, rather than assuming it's 0, alongside fixing a few places where things break / we encode the 0 == DefaultAS assumption. A bunch of existing tests are extended to check for non-zero default AS usage.
[DAG] visitABD - rewrite "(abs x, 0)" folds to use SDPatternMatch
No need for this to be vector specific, and its more likely that scalar cases will appear after #92576
[DAG] visitAVG - rewrite "fold (avgfloor x, 0) -> x >> 1" to use SDPatternMatch
No need for this to be vector specific, and its more likely that scalar cases will appear after #92096
