    c++: simplify enclosing_instantiation_of [PR95870]

    Comparing DECL_SOURCE_LOCATION like the GCC 11 patch for PR 95870 will also
    work for user-defined functions, if we update their location when
    instantiating.  Another option would be to use LAMBDA_EXPR_REGEN_INFO for
    lambdas, but this way is even simpler.

    gcc/cp/ChangeLog:

            PR c++/95870
            * pt.c (enclosing_instantiation_of): Just compare
            DECL_SOURCE_LOCATION.
            (regenerate_decl_from_template): Copy DECL_SOURCE_LOCATION.
