C++ PATCH: trivial cleanup

[Marek Polacek]

Use the proper type for "complain".

I guess it's obvious, but anyway, bootstrapped/regtested on x86_64-linux, ok
for trunk?

2018-09-21  Marek Polacek  <polacek@redhat.com>

	* cp-tree.h (build_noexcept_spec, add_exception_specifier): Adjust
	declarations.
	* except.c (build_noexcept_spec): Change the type of the complain
	parameter to tsubst_flags_t.
	* typeck2.c (add_exception_specifier): Likewise.
