middle-end/97162 - fix ICE when building gamess

Browse Source 
This appropriately guards the check for a hard register in
compare_base_decls which otherwise ICEs when passed a CONST_DECL.

2020-09-23  Richard Biener  <rguenther@suse.de>

	PR middle-end/97162
	* alias.c (compare_base_decls): Use DECL_HARD_REGISTER
	and guard with VAR_P.
