* store immediate values as int64_t, not int. come on, we should be happy
...
when there are immediates, let's not worry about the memory overhead of
this :)
* add addU64Imm(uint64_t val) to machineinstrbuilder
(seriously: this seems required to support 64-bit immediates cleanly. if it
_really_ gets on your nerves, feel free to pull it out ;) )
coming up next week: "all your floating point constants are belong to us"

Instead of storing std::string's for ExternalSymbol references, rely on the
...
fact that all ExternalSymbols are actually string literals with static storage.
Thus we don't have to do anything special to hold them and we certainly don't
have to copy string data around.

Allow machine operands to represent global variables with offsets. This is
...
useful when you have a reference like:
int A[100];
void foo() { A[10] = 1; }
In this case, &A[10] is a single constant and should be treated as such.
Only MO_GlobalAddress and MO_ExternalSymbol are allowed to use this field, no
other operand type is.
This is another fine patch contributed by Jeff Cohen!!

Continue Alkis's int64_t cleanup. This makes all of the immediate related

methods take an int or unsigned value instead of int64_t.
Also, add an 'addImm' method to the MachineInstrBuilder class, because the
fact that the hardware sign or zero extends it does not/should not matter
to the code generator. Once the old sparc backend is removed the difference
can be eliminated.

Change interface of MachineOperand as follows:
...
a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse()
b) add isUse(), isDef()
c) rename opHiBits32() to isHiBits32(),
opLoBits32() to isLoBits32(),
opHiBits64() to isHiBits64(),
opLoBits64() to isLoBits64().
This results to much more readable code, for example compare
"op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used
very often in the code.
