[LLVMbugs] Warning in TargetInstrInfo.h

[Vladimir Merzliakov]

Last nighttest run show new warnings:

lib/CodeGen/InstrSched//usr/home/wanderer/pkg/build/llvm/night/build/llvm/in
clude/llvm/Target/TargetInstrInfo.h:: warning: no return statement in
function returning non-void

Source problem is

  virtual MachineBasicBlock::iterator
  reverseBranchCondition(MachineBasicBlock::iterator MI) const {
    assert(0 && "Target didn't implement reverseBranchCondition!");
  }

I can propose 2 variants of warning fixing:

1) add "return MI;"
2) add no retrun function call: "abort();"

after assert.

Also exist variant:
3) ignore warning :)
