Series Fix fmv mangling for AArch64 |

Commit Message

Andrew Carlotti Jan. 15, 2024, 11:26 a.m. UTC 
  These tests are not intended to designate "correct" behaviour, but are
instead intended to demonstrate current behaviour, and provide a warning
if subsequent patches might lead to compatibility issues for targets
with existing function multiversioning support.
