Apparently the GNU assembler has a HUGE hack to be compatible with really
...
old and broken AT&T syntax assemblers. The problem with this hack is that
*SOME* forms of the fdiv and fsub instructions have the 'r' bit inverted.
This was a real pain to figure out, but is trivially easy to support: thus
we are now bug compatible with gas and gcc.

Changes recommended by Chris:
...
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.

Added the llvm.readport and llvm.writeport intrinsics for x86. These do
...
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.
