Revert r307529 "This patch completely replaces the scheduling information for the SandyBridge architecture"
This caused PR34080, which seems to have been fixed by r310792, but that change
introduced severe performance regressions.
Reverting to unblock the 5.0.0 release while these issues are worked out on trunk.
Also reverting a few tests that were added later and depended on the new scheduling:
LLVM :: CodeGen/X86/f16c-schedule.ll
LLVM :: CodeGen/X86/lea32-schedule.ll
LLVM :: CodeGen/X86/lea64-schedule.ll
LLVM :: CodeGen/X86/popcnt-schedule.ll
