  [JSC] Use offlineasm globl to ensure that all entries have alt_entry

Reviewed by Justin Michaud.

We found that vmEntryToCSSJIT and vmEntryToCSSJITAfter are not having alt_entry properly since it is not using offlineasm globl.
This allowed LLInt code shuffled by linkers when alt_entry is used, which breaks many assumptions. This patch fixes it.
