  Delete copy-ctor of MachineFrameInfo.

I just hit a nasty bug when writing a unit test after calling MF->getFrameInfo()
without declaring the variable as a reference.

Deleting the copy-constructor also showed a place in the ARM backend which was
doing the same thing, albeit it didn't impact correctness there from the looks of it.
