gccrs: asm: Fix clang warnings

Fixes a couple of warnings thrown by clang, with mismatched class/struct
usages and unused members.

gcc/rust/ChangeLog:

	* ast/rust-expr.h: Remove invalid usage of `struct`.
	* backend/rust-compile-asm.h: Remove unused `translated` member.
	* backend/rust-compile-asm.cc (CompileAsm::CompileAsm): Remove usage
	of `translated` member.
	* checks/errors/rust-unsafe-checker.h: Mark visitor as `override`.
	* hir/tree/rust-hir-expr.h (struct AnonConst): Remove unused `locus`
	member.
