Change ABI setup and add gccrs_proc_macro attr
Change the way the ABI is setup on a function to avoid duplicates. ABI
is setup by the setup function only now. Add a new attribute to the
function "gccrs_proc_macro" in order to differentiate it from another
type of function.
gcc/rust/ChangeLog:
* backend/rust-compile-base.cc (handle_proc_macro_common): Add
new attribute "gccrs_proc_macro" to all procedural macro
functions.
(get_abi): Add a function to retrieve the correct ABI depending
on wether the function is a proc macro or not.
