YJIT: Save PC and SP before calling leaf builtins (#7090)
Previously, we did not update `cfp->sp` before calling the C function of
ISEQs marked with `Primitive.attr! "inline"` (leaf builtins). This
caused the GC to miss temporary values on the stack in case the function
allocates and triggers a GC run. Right now, there is only a few leaf
builtins in numeric.rb on Integer methods such as `Integer#~`. Since
these methods only allocate when operating on big numbers, we missed
this issue.
Fix by saving PC and SP before calling the functions -- our usual
protocol for calling C functions that may allocate on the GC heap.
[Bug #19316]
