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.

Moved buildReg2RegClassMap() into from X86RegisterInfo to MRegisterInfo, since
...
it is target-independent.

Oops. Got the MOVrm and MOVmr mixed up. Fixed. We can now print out
...
instructions correctly.

Added methods to read/write values to stack in .h, fixed implementation in
...
.cpp to return the iterator correctly.

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.

Initial checkin of X86 backend.
...
We can instruction select exactly one instruction 'ret void'. Wow.
