[PR middle-end/106432] Gracefully handle unsupported type in range_on_edge

Browse Source 
A cleaner approach to fix this PR has been suggested by Andrew, which
is to just return false on range_on_edge for unsupported range types.

Tested on x86-64 Linux.

	PR middle-end/106432

gcc/ChangeLog:

	* gimple-range.cc (gimple_ranger::range_on_edge): Return false
	when the result range type is unsupported.
