c++: fix ICE with __type_pack_element [PR113834]
Here we crash on this invalid code because we seem to infinitely recurse
and end up with __type_pack_element with index that doesn't tree_fits_shwi_p
which then crashes on tree_to_shwi.
Thanks to Jakub for suggesting a nicer fix than my original one.
PR c++/113834
gcc/cp/ChangeLog:
* semantics.cc (finish_type_pack_element): Perform range checking
before tree_to_shwi.
gcc/testsuite/ChangeLog:
* g++.dg/ext/type_pack_element4.C: New test.
