  [ObjectSizeOffsetVisitor] Bail after visiting 100 instructions (#67479)

We're running into stack overflows for huge functions with lots of phis.
Even without the stack overflows, this is recursing >7000 in some
auto-generated code.

This fixes the stack overflow and brings down the compile time to
something reasonable.
