gccrs: Fix ICE when doing shift checks on const decl
Const decls are just delcarations wrapping the value into the DECL_INITIAL
and the shift checks we have assume no decls are involved and its just flat
values. This patch simply unwraps the constant values if they exist.
Fixes Rust-GCC#3665
gcc/rust/ChangeLog:
* rust-gcc.cc (arithmetic_or_logical_expression): unwrap const decls
gcc/testsuite/ChangeLog:
* rust/compile/issue-3665.rs: New test.
