[JSC] Make all slow-path calls for IC thunk in BaselineJIT DataIC
https://bugs.webkit.org/show_bug.cgi?id=261480
rdar://115392198
Reviewed by Mark Lam.
Now we aligned all register usage in BaselineJIT DataIC. So we can just use
DataIC
slow path thunk in all places including more complicated opcodes.
1. instanceof should have slow path thunk in the same way to the other IC. Just
doing it.
2. iterator_next / iterator_open includes some complicated get_by_id ops inside
it.
Let's use get_by_id's slow path thunk in the slow path of them. This is
totally OK since
they are using the same registers to get_by_id.
