This issue is similar to PR 87480; in both cases we were doing non-dependent
substitution with processing_template_decl set, leading to member access
expressions seeming still instantiation-dependent, and therefore decltype
not being simplified to its actual type.  And as in that PR, the fix is to
clear processing_template_decl while substituting a default template
argument.

I think there's a typo in the documentation of the MINLOC and MAXLOC intrinsics.

CSE does not consider calls, not even const calls.  This patch puts a
