Manman Ren f019cd62da Debug Info: LiveDebugVarible can remove DBG_VALUEs, make sure we emit them back. ...

RegisterCoalescer used to depend on LiveDebugVariable. LDV removes DBG_VALUEs
without emitting them at the end.

We fix this by removing LDV from RegisterCoalescer. Also add an assertion to
make sure we call emitDebugValues if DBG_VALUEs are removed at
runOnMachineFunction.
