[JSC] Enable Megamorphic Cache for enumerator_put_by_val /
enumerator_get_by_val in upper tiers
https://bugs.webkit.org/show_bug.cgi?id=269129
rdar://122689419
Reviewed by Mark Lam.
This patch enables embedded DFG / FTL megamorphic cache for
enumerator_put_by_val / enumerator_get_by_val.
We obtain PutByStatus / GetByStatus, and if it says "this was megamorphic in
lower tiers", then we use PutByValMegamorphic / GetByValMegamorphic.
