Prevent raw reference from being lowered silently
We do not handle those kind of references yet, we shall not let them
pass as a regular reference.
gcc/rust/ChangeLog:
* ast/rust-expr.h: Add a getter for mutability.
* hir/rust-ast-lower-expr.cc (ASTLoweringExpr::visit): Panic when a
raw reference is met.
