glr2.cc: fix -Wnoexcept issues
440-453 and 685 failed with GCC 12.1:
```
test.cc:1814:21: required from here
/opt/local/include/gcc12/c++/bits/stl_construct.h:95:14: error: noexcept-expression evaluates to 'false' because of a call to '{anonymous}::glr_stack_item::glr_stack_item(bool)' [-Werror=noexcept]
95 | noexcept(noexcept(::new((void*)0) _Tp(std::declval<_Args>()...)))
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
test.cc:1486:5: note: but '{anonymous}::glr_stack_item::glr_stack_item(bool)' does not throw; perhaps it should be declared 'noexcept'
1486 | glr_stack_item (bool state = true)
| ^~~~~~~~~~~~~~
```
