[Debugify] Add debug intrinsics before terminating musttail calls

After r333856, opt -debugify would just stop emitting debug value
intrinsics after encountering a musttail call. This wasn't sufficient to
avoid verifier failures.

Debug value intrinicss for all instructions preceding a musttail call
must also be emitted before the musttail call.

[InstCombine] Don't strip function type casts from musttail calls

Summary:
The cast simplifications that instcombine does here do not make any
attempt to obey the verifier rules for musttail calls. Therefore we have
to disable them.
