testsuite: Force max-completely-peeled-insns=300 for CRIS, PR118055

This handles fallout from r15-6097-gee2f19b0937b5e.  A brief
analysis shows that the metric used in that code is computed
by estimate_move_cost, differentiating on the target macro
MOVE_MAX_PIECES (which defaults to MOVE_MAX) which for most
"32-bit targets" is 4 and for "64-bit targets" is 8.  There
are some outliers, like pru, with MOVE_MAX set to 8 but
counting as a 32-bit target.

So, the main difference for this test-case, which is heavy
on 64-bit moves (most targets have "double" mapped to IEEE
64-bit), is between "32-bit" and "64-bit", with the cost up
to twice for the former compared to the latter.  I see no
effective_target_move_max_is_4 or equivalent, and this
instance falls below the threshold of adding one, so I'm
sticking to a list of targets.  For CRIS, it would suffice
with 210, but there's no need to be this specific, and it
would make the test even more brittle.

	PR tree-optimization/118055
	* gcc.dg/tree-ssa/pr83403-1.c, gcc.dg/tree-ssa/pr83403-2.c: Add
	cris-*-* to targets passing --param=max-completely-peeled-insns=300.
