The testcase is the work-around testcase for the PR; even that had
started failing.  The problem was that, when unqualifying the type of
a TARGET_EXPR, we'd create a variant of the type, then request the
conversion of the TARGET_EXPR_INITIAL to that variant type.  Though
the types are different pointer-wise, they're the same_type_p, so the
resulting modified expr compares cp_tree_equal to the original, which
maybe_constant_value flags as an error.  There's no reason to
construct an alternate TARGET_EXPR or CONSTRUCTOR just because of an
equivalent type, except for another spot that expected pointer
equality that would no longer be satisfied.  Without relaxing the
assert in constexpr_call_hasher::equal, g++.robertl/eb73.C would
trigger an assertion failure.

    In buildmodeinit, the c-archive buildmode is flagged as invalid
    on linux/ppc64 for gccgo when it should be valid. This happens
    because the check against the gccgo flag is done after the checks
    for valid GOOS/GOARCH pairs instead of before as is done for all
    other buildmode cases in this switch. This corrects the problem and
    allows several of the gccgo gotools testcases to pass on linux/ppc64.
