Hi,

with -march=z10 we use much higher values for peel and unroll limits.
This makes the loop in the testcase to disappear on tree level
already.  With the patch these values are set back to the default
values making the testcase to pass again.

Committed to mainline

Bye,

-Andreas-

	* gcc.dg/var-expand1.c: Force max-completely-peel-times and
	max-unroll-times back to defaults for s390.
