    c++: non-dep init folding and access checking [PR109480]

    enforce_access currently checks processing_template_decl to decide
    whether to defer the given access check until instantiation time.
    But using this flag is unreliable because it gets cleared during e.g.
    non-dependent initializer folding, and so can lead to premature access
    check failures as in the below testcase.  It seems better to check
    current_template_parms instead.

            PR c++/109480

    gcc/cp/ChangeLog:

            * semantics.cc (enforce_access): Check current_template_parms
            instead of processing_template_decl when deciding whether to
            defer the access check.

    gcc/testsuite/ChangeLog:

            * g++.dg/template/non-dependent25a.C: New test.=
