gccrs: catch missing guard for optional result
When we lookup here it returns an optional which can lead to a crash because it needs a guard if it has a value. gcc/rust/ChangeLog: * backend/rust-compile-resolve-path.cc (HIRCompileBase::query_compile): add guard gcc/testsuite/ChangeLog: * rust/compile/nr2/exclude: these tests now work it seems Signed-off-by: Philip Herron <herron.philip@googlemail.com>
