re PR target/65103 ([i386] GOTOFF relocation is not propagated into address expression) 

gcc/

	PR target/65103
	* config/i386/i386.c (ix86_rtx_costs): We want to propagate
	link time constants into adress expressions and therefore set
	their cost to 0.

gcc/testsuite/

	PR target/65103
	* gcc.target/i386/pr65103-3.c: New.
