In the Z backend we still set min-vect-loop-bound to 2 to work around
corner cases where awkward epilogue code gets generated in the
vectorizer.  This has a particular bad impact when vectorizing loops
with a low iteration count.  Due to this we do not vectorize the loop
in gen-vect-11/32 - what actually is a pity.

The patch sets min-vect-loop-bound back to the default value of 0 in
order to enable vectorization.

2019-11-05  Andreas Krebbel  <krebbel@linux.ibm.com>

	* gcc.dg/tree-ssa/gen-vect-11.c: Add --param min-vect-loop-bound=0
	for IBM Z.
	* gcc.dg/tree-ssa/gen-vect-23.c: Likewise.

This fixes various issues with the useable_hw check in s390.exp.  The
check is supposed to verify whether a testcase can be run on the
current hardware.

- the test never returned true for -m31 because vzero is not available
  in ESA mode and -m31 defaults to -mesa
- the missing v0 clobber on the vzero instruction made the check fail
  if the stack pointer got saved in f0
- the lcbb instruction used for checking whether we are on a z13
  also requires vx.  Replace it with an instruction from the generic
  instruction set extensions.
- no support for z14 and z15 so far
