gccrs: Change return type of lookup_hir_extern_block
Change the return type to an optional in order to easily differentiate between a null pointer and an missing value. gcc/rust/ChangeLog: * checks/errors/rust-unsafe-checker.cc (UnsafeChecker::check_function_call): Adapt function call to new return type. * typecheck/rust-type-util.cc (query_type): Likewise. * util/rust-hir-map.cc (Mappings::insert_hir_extern_block): Likewise. (Mappings::lookup_hir_extern_block): Change return type to an optional. * util/rust-hir-map.h: Update the function's prototype.
