[lldb] Fix asan failures in data-formatter-objc tests
The test is currently failing on some systems with ASAN enabled due to:
==22898==ERROR: AddressSanitizer: heap-buffer-overflow on address

The reason is that we create a string "HELLO" but get the size wrong
(it's 5 bytes instead of 4). Later on we read the buffer and pretend it
is 5 bytes long, causing an OOB read which ASAN detects.
In general this test probably needs some cleanup as it produces on macOS
10.15 around 100 compiler warnings which isn't great, but let's first
get the bot green.

constants along with tests.

Commit ed181efa175d3e0acc134e6cd161914e64c7195e by sameer.sahasrabuddhe
[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
