merge revision(s) 31e67a476f2262e01a0829e8ab5e6d8a97e0724e,0b95cbcbde8875effdbcbb676cb0a7f751a1d4c1: [Backport #19601]

	YJIT: Fix false object collection when setting ivar

	Previously, setinstancevariable could generate code that calls
	`rb_ensure_iv_list_size()` without first updating `cfp->sp`. This means
	in the event that a GC start from within said routine the top few
	objects would not be marked, causing them to be falsly collected.

	Call `jit_prepare_routine_call()` first.

	[Bug #19601]

	YJIT: Remove duplicate `asm.spill_temps()`

	`jit_prepare_routine_call()` calls it, and there is another call above on line 2302.
