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.
