The TypeCheckExpr creates a new TyTy::BoolType for a
ComparisonExpr. This new BoolType is unknown to TyTyResolveCompile
which causes a crash when trying to compile the inferred new
BoolType. The new "bools_eq.rs" testcase uses several bools which show
this issue. Resolve this by looking up the builtin bool type.
