Can you do a bisection to identify the exact commit responsible? Looking at
the original commit that introduced the movt md pattern (139881) I see a
TARGET_USE_MOVT guard in the C code that _should_ prevent it from being
selected on non Thumb2-capable CPUs. If these guards are now broken then they
need to be fixed.
