Support noexnref and exnref casting
https://bugs.webkit.org/show_bug.cgi?id=286180
rdar://142982391
Reviewed by Yusuke Suzuki.
noexnref / nullexn was not implemented with the new exception specification.
This patch adds support for noexnref, and cleans up issues with interactions
between the new exception spec and the GC spec when casting exnrefs.
