[AMDGPU] Disable atomic optimizer for single lane execution (#187915)
Optimized IR will have worse performance when only a single lane is
active. Disable optimizer when single lane is expected at compile time.
[llc] Fix -mcpu=help for default target triple (#187878)
Previously, a command like `llc -mcpu=help` would fail on invalid target
triple, due to wrongly passing empty target to `Triple::normalize`
resulting in `unknown`.
[opt] Enable -mcpu=help without an input file (#187876)
This patch enables `-mcpu=help` or `-mattr=help` invocation without an
input file, like `llc`. For example, the following command `opt
-mtriple=aarch64 -mattr=help` would previously hang but now it succeeds.
The implementation is similar to llc, creating a target machine for help
printing side effects and existing early. Note: llc has a bug in the
default triple handling that we already fix here upfront. Ill submit a
separate fix for llc.
[ASan] Enable __SANITIZER_DISABLE_CONTAINER_OVERFLOW__ tests (#181721)
Now that the corresponding libcxx change has landed, these tests should
be passing on some platforms.
This patch re-enables them for all platforms, so that we can see which
bots these do not work on and mark them unsupported accordingly.

[LegalizeTypes] Keep non-negative info in SUB(CTLZ) (#186338)
When legalizing CTLZ for a wider type with a SUB bit-width compensation,
the result for a zero-defined case can have an extra bit that exceeds
the maximum value of the original type width. Unlike CTLS, which covers
all bits within its type width, CTLZ leads to producing undefined
KnownBits. So, after subtraction, the KnownBits could represent a
negative value, which prevents subsequent optimizations.
This patch ensures that non-negative information is preserved during the
SUB(CTLZ) expansion, so that KnownBits after SUB will take a stricter
range within the type width, thus allowing further combine optimizations
following by SUB. Particularly, this enables the DAG Combiner to remove
unnecessary AND instructions for CTLZ output type conversion.
Fixes #136516

acpi_spmc: Fix checking expected DSMs
Previously was or'ing the indices of the DSMs directly, not their
corresponding bits. This commit rectifies this.

[libclc][NFC] Remove __CLC_BIT_INTN macro (#188023)
This macro was originally introduced in 64735ad63975 for relational
built-ins. It is functionally identical to __CLC_S_GENTYPE. Replacing it
simplifies gentype.inc, which is widely used in the library.
[C++20] [Modules] Apply DeclUpdate lazily in reduced BMI (#175498)
Previously we will apply all decl update unconditionally, but it might
not be best. See the attached example
'class-instantiate-no-change-02.cppm' for example. Sometimes these BMIs
are reducible.
