	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]
