(odr_type_d): Add field rtti_broken.
(odr_subtypes_equivalent_p): Do not require name to match.
(compare_virtual_tables): Fix typo; if type already has ODR violation,
bypass the tests; be ready for function referneces in vtables that are
not DECL_VIRTUAL; make warnings to be OPT_Wodr.
(warn_odr): Give up for nameless types.
(warn_types_mismatch): Report mismatch in mangled names;
report mismatch in anonymous namespaces; look into component types to
give useful error; report when mismatch is dragged in from other ODR
type.
(odr_types_equivalent_p): Match types for being polymorphic; avoid
duplicated diagnostics.
(add_type_duplicate): Reorder checks so more informative ones come
first; fix typo; do not output "the extra base is defined here" when
we did not warn.
(BINFO_N_BASE_BINFOS): Relax sanity check.

* config/rs6000/predicates.md (easy_fp_constant): Remove special
-ffast-math handling that kept non-0 constants live in the RTL
until reload. Remove logic testing the number of instructions it
took to create a constant in a GPR that was never used, due to a
test for soft-float earlier.

* config/rs6000/rs6000.md (mov<MODE>_hardfloat): Remove
alternatives for loading non-0 constants into GPRs for hard
floating point that is no longer needed due to changes in
easy_fp_constant. Add support for loading 0.0 into GPRs.
