Working on it.  The obvious fix does not fix it.

I think this regression is due to r153793, which was Tobias' fix for PR41850.

The reason for the ICE is that the formal argument mask of
_gfortran_mmaxloc0_4_r4 has as = NULL (while the actual argument has
nonzero rank). I'm not sure if the missing array spec is special to MAXLOC, or
if this is the case for all intrinsics.
