inliner: Don't ICE on NULL TYPE_DOMAIN [PR94621]

When I've added the VLA tweak for OpenMP to avoid error_mark_nodes in the
IL in
type, I forgot that TYPE_DOMAIN could be NULL.  Furthermore, as an
optimization,
this patch checks the hopefully cheapest condition that is very likely
false
most of the time (enabled only during OpenMP handling) first.

PR tree-optimization/94621
* tree-inline.c (remap_type_1): Don't dereference NULL TYPE_DOMAIN.
Move id->adjust_array_error_bounds check first in the condition.

* gcc.c-torture/compile/pr94621.c: New test.
