cc65beeb39 Two changes here: 
1. Add new instructions for checking parity flags: JP, JNP, SETP, SETNP.
2. Set the isCommutable and isPromotableTo3Address bits on several
   instructions.

It's stosl (l for long == 32 bit).

10f873b420 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.

3a173dfc72 Add support to the instruction patterns for AT&T style output, which will 
hopefully lead to the death of the 'GasBugWorkaroundEmitter'.  This also
includes changes to wrap the whole file to 80 columns! Woot! :)

Note that the AT&T style output has not been tested at all.

978f629ba9 A call instruction should implicitely define ST0 since the return 
value is returned in that register. The pseudo instructions
FpGETRESULT and FpSETRESULT shold also have an implicity use and def
of ST0 repsecitvely.

ca6ea0f137 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.

4ffff9e2fa 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.
