[HIP][AMDGPU] expand printf when compiling HIP to AMDGPU
Summary: This change implements the expansion in two parts:
- Add a utility function emitAMDGPUPrintfCall() in LLVM.
- Invoke the above function from Clang CodeGen, when processing a HIP
program for the AMDGPU target.
The printf expansion has undefined behaviour if the format string is not
a compile-time constant. As a sufficient condition, the HIP ToolChain
now emits -Werror=format-nonliteral.

[LV] Make X86/assume.ll X86 independent (NFC).
The test does not check anything X86 specific. This is a preparation for
the D68814.

Commit 23c113802e21253332dc41fba6639106b7b1e461 by flo
[LV] Allow assume calls in predicated blocks.
The assume intrinsic is intentionally marked as may reading/writing
memory, to avoid passes moving them around. When flattening the CFG for
predicated blocks, we have to drop the assume calls, as they are
control-flow dependent.
There are some cases where we can do better (when control flow is
preserved), but that is follow-up work.
Fixes PR43620.

clang-format: [JS] tests for async wrapping.
Summary: Adds tests to ensure that `async method() ...` does not wrap
between async and the method name, which would cause automatic semicolon

[IR] Mark memset.* intrinsics as IntrWriteMem.
llvm.memset intrinsics do only write memory, but are missing
IntrWriteMem, so they doesNotReadMemory() returns false for them.
The test change is due to the test checking the fn attribute ids at the
call sites, which got bumped up due to a new combination with writeonly
appearing in the test file.

[clangd] Dont display `<unknown>` kinds in hover board
Summary: Currently when hovering over an `auto` or `decltype` that
resolve to a builtin-type, clangd would display `<unknown>` as the kind
of the symbol.
Drop that to make rendering nicer.
