r253236 broke AArch64 bootstrap. This is a temporary workaround that disables qsort checking in the scheduler to enable continued development and testing on AArch64.

vec_ceil and friends are expanded by vecintrin.h to __builtin_s390_vfi which is an overloaded builtin being replaced by either __builtin_s390_vfisb or __builtin_s390_vfidb depending on its argument types.

vec_unpacks_hi_v4sf/vec_unpacks_lo_v4sf expand vec_mergeh and vec_mergel patterns also for z13 with V4SF modes so the patterns should better accept this. Fixed by changing the mode iterator to V_128_NOSINGLE which accepts V4SF unconditionally. gcc/ChangeLog: 2017-10-04 Andreas Krebbel <krebbel@linux.vnet.ibm.com> * config/s390/vx-builtins.md ("vec_mergeh<mode>") ("vec_mergel<mode>"): Change mode iterator to V_128_NOSINGLE.
