DFG is still too pessimistic about what constitutes a side-effect on array accesses
https://bugs.webkit.org/show_bug.cgi?id=94309
Reviewed by Geoffrey Garen.
This change means that even if structure transition watchpoints are not used for
hoisting of clobbered structure checks, we still retain good performance on the
benchmarks we care about. That's important, since butterflies will likely make
most array structures not watchpointable.
