gccrs: remove braces around scalar initializers

Remove useless braces around scalar initializers. This will also remove
some warning emitted by the compiler and avoid cluttering it's output.

gcc/rust/ChangeLog:

	* backend/rust-compile-intrinsic.cc (offset_handler): Remove
	braces.
	(sizeof_handler): Likewise.
	(transmute_handler): Likewise.
	(rotate_handler): Likewise.
	(wrapping_op_handler_inner): Likewise.
	(op_with_overflow_inner): Likewise.
	(atomic_load_handler_inner): Likewise.
	(unchecked_op_inner): Likewise.
	(uninit_handler): Likewise.
