	[PATCH] Correctly compile splats in for-loop index in prism

	Fixes [Bug #21648]

	This is a followup to https://github.com/ruby/ruby/pull/13597.
	The added test passed but didn't emit the same instructions.

	This also handles bare splats and aligns instructions for all cases

	[Bug #21439] Fix `PM_SPLAT_NODE` compilation error in for loops (#13597)

	[Bug #21439] Fix PM_SPLAT_NODE compilation error in for loops

	This commit fixes a crash that occurred when using splat nodes (*) as
	the index variable in for loops. The error "Unexpected node type for
	index in for node: PM_SPLAT_NODE" was thrown because the compiler
	didn't know how to handle splat nodes in this context.

	The fix allows code like `for *x in [[1,2], [3,4]]` to compile and
	execute correctly, where the splat collects each sub-array.

	Correctly set node_id on iseq location

	The iseq location object has a slot for node ids.  parse.y was correctly
	populating that field but Prism was not. This commit populates the field
	with the ast node id for that iseq
