  Log Message:
  -----------
  Moved all register saving/restoring functions to one of two new classes
and removed the definitions from the inst-aarch64 header.

This commit moves all functions that handle register saving/restoring
for the base tramp to one of two new classes: EmitterAARCH64SaveRegs and
EmitterAARCH64RestoreRegs. The class definitions go in the emit-aarch64
file with their implementation in the inst-aarch64 file.

baseTramp::generateSaves/generateRestores will have an instance of one
of these classes as appropriate and call only the public methods of the
class. None of the methods for saving/restoring individual regs are now
public: the only public methods are those that save/restore ALL
GPRs/FPRs/SPRs.
