Subject: [PATCH] [AMDGPU][NFC] Pre-commit test for integer
 raw.ptr.buffer.load.format

llvm.amdgcn.raw.ptr.buffer.load.format is restricted to floats for
some reason, even though it doesn't need to be (per its non-`.ptr`
counterpart). Pre-commit tests for the integer form.

AI disclosure: Claude wrote these tests, I wrote the message, the big
comment is temporary.
