Oops, sorry.

The following patch should fix that and should also fix streaming of the
new explicit_mask_* members.

2020-10-05  Jakub Jelinek  <jakub@redhat.com>

	* opth-gen.awk: Don't emit explicit_mask array if n_target_explicit
	is equal to n_target_explicit_mask.
	* optc-save-gen.awk: Compute has_target_explicit_mask and if false,
	don't emit code iterating over explicit_mask array elements.  Stream
	also explicit_mask_* target members.
