gccrs: Change lookup_hir_expr return type to optional
Wrap the function's return type with an optional in order to
differentiate missing values from null pointers.
gcc/rust/ChangeLog:
* backend/rust-mangle-v0.cc (v0_path): Adapt call site to new returned
type.
* util/rust-hir-map.cc (Mappings::lookup_hir_expr): Change the
function's return type.
* util/rust-hir-map.h: Update the function's prototype.
