The following patch fixes an almost obvious ICE in invalid.

Regtested on x86_64-pc-linux-gnu.

OK for master, and backports to 9/10?

Thanks,

The check for assigning a pointer that cannot be determined to be simply
contiguous at compile time to a contiguous pointer does not need to be
invoked if the lhs of the assignment is known to have conflicting attributes.
