gccrs: Parse raw ref operator
The raw ref operator is an unstable feature required to obtain a pointer
to unaligned adresses (mainly unaligned struct fields) without UB.
gcc/rust/ChangeLog:
* ast/rust-ast-builder.cc (Builder::ref): Adapt constructor to the new
API.
* ast/rust-ast-collector.cc (TokenCollector::visit): Emit a raw weak
keyword when required.
* ast/rust-ast.cc (BorrowExpr::as_string): Change as_string
representation to handle raw ref operator.
* ast/rust-expr.h (class BorrowExpr): Add raw discriminant.
* expand/rust-macro-builtins-include.cc: Adapt constructor to the new
API.
* parse/rust-parse-impl.h: Handle the raw weak keyword.
