IBM Z: Fix testsuite useable_hw check
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
gcc/testsuite/ChangeLog:
2019-11-05 Andreas Krebbel <krebbel@linux.ibm.com>
* gcc.target/s390/s390.exp
(check_effective_target_s390_useable_hw): Add inline asm for z14
and z15. Replace instruction for z13 with lochiz. Add register
clobbers. Check also for __zarch__ when doing the __VX__ test.
