ba1c1da36a Move handing of GlobalValues from getReg() to copyConstantToRegister(), this
will avoid extra register-to-register copies.  Thanks to Chris for the idea.

61114619bc * Fn args passed in registers are now recorded as used by the call instruction
`-> asm printer updated to not print out those registers with the call instr

All of Shootout tests now work.  Great thanks to Nate Begeman for the patch!

bebde759e5 * Use LI(S) to copy constants into registers intead of ADDI(S) as the latter is
a funky way to "use" R0 for a 0-valued operand
* Add IMPLICIT_DEFs for incoming function arguments via registers to help the
  register allocator not clobber those registers
* Implement comparisons with longs
* Teach emitSelectOperation() to fold the SetCC operation

d2995df5b7 Improve codegen for the LLVM offsetof/sizeof "operator". Before we compiled
this LLVM function:

int %foo() {
        ret int cast (int** getelementptr (int** null, int 1) to int)
}

into:

foo:
        mov %EAX, 0
        lea %EAX, DWORD PTR [%EAX + 4]
        ret

now we compile it into:

foo:
        mov %EAX, 4
        ret

This sequence is frequently generated by the MSIL front-end, and soon the malloc lowering pass and
Java front-ends as well..
