Log Message:
-----------
[JSC] ref.func in init-expr should be validated with function-index-space
https://bugs.webkit.org/show_bug.cgi?id=251542
rdar://104911237
Reviewed by Mark Lam.
Use functionIndexSpaceSize for validation for ref.func in init-expr, since
ref.func takes functionIndexSpace.
Note that functionIndexSpaceSize is always larger than functionIndex's size. We
were wrongly rejecting valid
ref.func via validation.
