InstSelectSimple.cpp:
  Change the checks for proper I/O port address size into an exit() instead
  of an assertion.  Assertions aren't used in Release builds, and handling
  this error should be graceful (not that this counts as graceful, but it's
  more graceful).

  Modified the generation of the IN/OUT instructions to have 0 arguments.
X86InstrInfo.td:
  Added the OpSize attribute to the 16 bit IN and OUT instructions.

I/O port instructions on x86.  The specific code sequence is tailored to
the parameters and return value of the intrinsic call.
Added the ability for implicit defintions to be printed in the Instruction
Printer.
Added the ability for RawFrm instruction to print implict uses and
defintions with correct comma output.  This required adjustment to some
methods so that a leading comma would or would not be printed.

The Verifier ensures that their parameters are of integral types and have
the correct sign, but it does not enforce any size restrictions because
such restrictions are platform dependent.

Now we collect all of the call sites we are interested in inlining, then inline
them.  This entirely avoids issues with trying to inline a call site we got by
inlining another call site.  This also eliminates iterator invalidation issues.

function prologues, and fix an off-by-one in visitCallInst that was
putting call args into the wrong registers.

trying to get incoming args off the stack, instead of the %i0...%i6 regs,
which is wrong.

have no good way of handling this until the code generator is improved.
We should probably just emit V9 instructions in the meantime.

Preliminary support for division. It's gross because you have to initialize
the "Y" register, which is the top 32 bits of the thing you're dividing.

Don't put NOPs in delay slots at all. We'll have a fix-up pass later.
