re PR tree-optimization/59417 (ICE in determine_value_range, at tree-ssa-loop-niter.c:176)

	PR tree-optimization/59417
	* tree-ssa-copy.c (fini_copy_prop): If copy_of[i].value is defined
	in a different bb rhan var, only duplicate points-to info and
	not alignment info and don't duplicate range info.
	* tree-ssa-loop-niter.c (determine_value_range): Instead of
	assertion failure handle inconsistencies in range info by only
	using var's range info and not PHI result range infos.

	* gcc.c-torture/compile/pr59417.c: New test.
