gccrs: fix ICE on empty constexpr loops

Empty loops have no body which means this is a NULL_TREE during const
evaluation which needs a check. Fixes Rust-GCC #3618.

gcc/rust/ChangeLog:

* backend/rust-constexpr.cc (eval_constant_expression):  Check if t is a NULL_TREE

gcc/testsuite/ChangeLog:

* rust/compile/issue-3618.rs: Test empty loops error properly.
