812c488f0a Do IMPLICIT_DEFs on incoming args' hard regs, to avoid confusing the regalloc.
Support single-fp incoming args.
Support single-fp outgoing args ('call' operands).
Support double-fp return values.

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..

* Use the SetCC handling code in the format of Brian's V8
* Add FIXMEs where calls to functions are being made without adding them to the
  Module first... they cause missing symbols at assembly-time.

14d8c7a6a0 * Don't save LR when outputting globals: it's already saved on the stack once
for the function
* Registers aren't necessarily sequential wrt their enums, don't rely on it
  when emitting function arguments into sequential registers
* Remove X86-specific comments about AL/BL/AH/BH/EDX/etc
* Add an abort() for an unimplemented signed right shift
* The src operand for a GEP was never emitted!  Fixed.
* We can skip zero-valued GEP indices as they are no-ops.
