Some dummy cost model for s390x:
- Prefer short-imm instructions over ext-imm, when possible - Prefer Z10 instructions over Z9, when possible This hopefully should fix some dejagnu test fails on solaris git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79741 91177308-0d34-0410-b5e6-96231b3b80d8
