Message:

[JSC] FTL should handle LocalAllocator*
​https://bugs.webkit.org/show_bug.cgi?id=193980

Reviewed by Saam Barati.

At some point, Allocator holds LocalAllocator* instead of 32bit integer. In FTL allocation path, we fail to use this constant LocalAllocator*
because the FTL still use the incoming value as 32bit integer there.
