[JSC] Prevent SEGV triggered by exceptions from `Wasm::Global::get`
https://bugs.webkit.org/show_bug.cgi?id=294119
Reviewed by Justin Michaud.
Running the test case attached to 293340 on current JSC ends in a
segmentation fault.
That crash is itself a bug, so this patch adds proper handling for
the exception raised by global get and ensures JSC no longer SEGVs.
NOTE: This patch does not fix the functional bug reported in 293340;
it only removes the SEGV.
