[fast-isel] Add the -verify-machineinstrs to these test cases. The remaining test cases require fixes to fast-isel before the verifier can be enabled. Part of rdar://12594152 llvm-svn: 168233

Reapply r146997, "Heed spill slot alignment on ARM." Now that canRealignStack() understands frozen reserved registers, it is safe to use it for aligned spill instructions. It will only return true if the registers reserved at the beginning of register allocation allow for dynamic stack realignment. <rdar://problem/10625436> llvm-svn: 147579
