Treat longs as ints => pretend they're all 32-bit values and squeeze them into
...
32-bit registers.

Added moveReg2Reg() and moveImm2Reg() to accomodate moving data around due to
...
PHI nodes.

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.

...
instructions 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.

...
We can instruction select exactly one instruction 'ret void'. Wow.
