gccrs: Fix ICE on raw reference
This patch adds support for raw references which enforce the pointer
type away from a reference type.
Fixes Rust-GCC#3667
gcc/rust/ChangeLog:
* backend/rust-compile-base.cc (HIRCompileBase::address_expression): allow optional type
* backend/rust-compile-base.h: update prototype
* backend/rust-compile-expr.cc (CompileExpr::visit): update borrow expr
* backend/rust-compile-extern.h: remove unused debug
* backend/rust-compile-resolve-path.cc (HIRCompileBase::query_compile): update usage
* hir/rust-ast-lower-expr.cc (ASTLoweringExpr::visit): lower raw ref
* hir/tree/rust-hir-expr.cc (BorrowExpr::BorrowExpr): add flag for raw ref
* hir/tree/rust-hir-expr.h (class BorrowExpr): add new raw ref field
* typecheck/rust-hir-type-check-expr.cc (TypeCheckExpr::visit): add handle for raw ref
gcc/testsuite/ChangeLog:
* rust/compile/issue-3667.rs: New test.
