aarch64, testsuite: Prevent stp in lr_free_1.c

The test is looking for individual stores which are able to be merged
into stp instructions.  The test currently passes -fno-schedule-fusion
-fno-peephole2, presumably to prevent these stores from being turned
into stps, but this is no longer sufficient with the new ldp/stp fusion
pass.

As such, we add --param=aarch64-stp-policy=never to prevent stps being
formed.

gcc/testsuite/ChangeLog:

	* gcc.target/aarch64/lr_free_1.c: Add
	--param=aarch64-stp-policy=never to dg-options.
