From: Owen Avery <[email protected]>
This doesn't handle rustc_args_required_const, but it does allow us to
recognize it as a valid attribute.
gcc/rust/ChangeLog:
* util/rust-attribute-values.h
(Attributes::RUSTC_ARGS_REQUIRED_CONST): New constexpr variable.
* util/rust-attributes.cc (__definitions): New entry for
RUSTC_ARGS_REQUIRED_CONST.
