`Fixes:` is used to indicate the commit that introduced the code being
fixed, such as:
Fixes: 1c4e6d7ca83578caf521 ("nvc0/ir: propagate immediates to CALL input
MOVs")
This tag is used by our tools to backport fixes to the relevant stable
releases.
Bugzilla entries are referenced using the `Bugzilla:` prefix.

I'll admit I don't know anything about this code, but it looks like
this might be a better fix?
assert(ld == NULL || ld->getSrc(0) != NULL)
I cc'ed Tobias who wrote this code as he'll probably know best.
