Implemented functions for emitting prologues and epilogues;
...
removed EBP from the list of callee-saved registers (it isn't one).

storeReg2RegOffset() and loadRegOffset2Reg() now take the iterator by value
...
instead of by reference, since they return the modified iterator.

Add definitions for function headers from MRegisterInfo.h:
...
Some functions are in X86RegisterInfo.cpp, others, because of the data they
need, are in X86RegisterClasses.cpp, which also defines some register classes:
byte, short, and int.
