LOG: [AMX] Fix LIT test with adjustsStack attribute for expensive checks build. (#156808)

The generated MIR fails machine verifier as stack pointer is being
modified without appropriate attributes in frameInfo. This PR fixes this
issue by adding adjustsStack=true attribute. Fixes the post commit
regression identified in #155673.
