From: Philip Herron <herron.phi...@googlemail.com>
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
