From-SVN: r21967
* typeck.c (convert_for_assignment): Converting from pm of vbase
to derived is an error, not a sorry.
* call.c (build_over_call): Use convert_pointer_to_real for 'this'.
* class.c (fixed_type_or_null): Rename from
resolves_to_fixed_type_p. Return the dynamic type of the
expression, if fixed, or null.
(resolves_to_fixed_type_p): Use it. Return 0 if the dynamic type
does not match the static type.
(build_vbase_path): Rename 'alias_this' to 'nonnull'. Use
resolves_to_fixed_type_p again.
From-SVN: r21958
* loop.c (scan_loop): Allocate some slop to handle pseudos
generated by move_movables.
