Subject: [PATCH] [CK] Work around staging compiler lifetime warning (#4419)

## Motivation
The staging compiler enables lifetime-safety warnings and we already
worked around a few of them.
This works around a few more instances that came up recently on gfx950
builds.
The initial PR that resolved most issues:
https://github.com/ROCm/composable_kernel/pull/3640

## Technical Details
This follows the pattern to locally ignore the newly added
lifetime-safety warnings that were moved from experimental to production
in upstream LLVM.
As a result, CK turned them on and treats them as errors, which prevents
the staging compiler from building CK.

## Test Plan

## Test Result
