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.

GNAT was missing errors as well as issuing messages on legal lines in
new ACATS tests for illegal renamings of discriminant-dependent
components. Cases that are fixed include object names involving
qualified expressions, dereference cases, and generic formal access and
formal derived types. Better implements the "known to be constrained"
rules in the Ada RM.
Tested by new ACATS tests B85100[567] that are soon to be released.

* sem_aux.adb (Object_Type_Has_Constrained_Partial_View): Return
True for an untagged discriminated formal derived type when
referenced within a generic body (augments existing test for
formal private types).
* sem_util.adb (Is_Dependent_Component_Of_Mutable_Type): If the
prefix of the name is a qualified expression, retrieve the
operand of that. Add a test of whether the (possible)
dereference prefix is a variable, and also test whether that
prefix might just be of an access type (occurs in some implicit
dereference cases) rather than being an explicit dereference.
Retrieve the Original_Node of the object name's main prefix and
handle the possibility of that being a qualified expression.
Remove special-case code for explicit dereferences that don't
come from source. Add test for the renaming not being within a
generic body for proper determination of whether a formal access
type is known to be constrained (it is within a generic spec,
but not in the body). Fix an existing incorrect test for
renaming of a discriminant-dependent component of a untagged
generic formal type being within a generic body, adding test of
taggedness and calling In_Generic_Body (now properly checks for
cases where the renaming is in a nongeneric body nested within a
generic). Return False in cases where the selector is not a
component (or discriminant), which can occur for
prefixed-notation calls.

This patch fixes a spurious error on a array expression that is a
dependent expression of an if-expression, when the length of the array
matches that imposed by the context, but the bounds of both differ, in
particular when the expression and the context are both null arrays with
different bounds.
