37efe67645 JumpTable support! What this represents is working asm and jit support for 
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

9696a90ee6 * 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"

7b55d4fce2 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.

ca4f6ebefc 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!!

6a8a9b4413 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.

890f92328d Move MOTy::UseType enum into MachineOperand. This eliminates the 
switch statements in the constructors and simplifies the
implementation of the getUseType() member function. You will have to
specify defs using MachineOperand::Def instead of MOTy::Def though
(similarly for Use and UseAndDef).

alkis too.  :)

4d7af65903 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.

5e8b77e375 Completely eliminate the per-machine-instruction regsUsed set. 
This substantially shrinks the size of each machine instruction, which should
make allocation faster and the cache footprint of the machine code lighter.

This are timings of code generation phases of the X86 JIT, when compiled in

35880f394f Instead of checking op.getType() against MO_VirtualRegister and 
MO_MachineRegister, we no longer distinguish Virtual vs. Machine registers
externally, they're ALL registers, all equal.

Registers are only differentiated whether they are >=
MRegisterInfo::FirstVirtual or not.

7a4be9580e Moved class MachineCodeForBasicBlock to MachineCodeForBasicBlock.{cpp,h}. 
An (explicit or implicit) operand may now be both a def and a use.
Also add a set of regs used by each instruction.
dump() no longer takes an optional argument, which doesn't work in gdb.
