Fixes is only for bug fixes.  These don't fix any bugs.

How do you distinguish these in questionable source code
from other error categories or software weaknesses?

A style change is one that doesn't change the effect of the execution.
 These don't actually even change the assembly, so there's programmatic
proof they're not fixing anything.

Bug means potentially user visible fault.  In any bug fix commit you
should document the fault and its effects on users so those backporting
can decide if they care or not.
