Emit the immediate form of in/out when possible.
...
Fix several bugs in the intrinsics:
1. Make sure to copy the input registers before the instructions that use them
2. Make sure to copy the value returned by 'in' out of EAX into the register
it is supposed to be in.
This fixes assertions when using in/out and linear scan.

Corrected the descriptions of the llvm.writeport and llvm.writeio

intrinsics.
Modified llvm.readio and llvm.writeio to use pointers to memory instead
of integers. This should take care of problems such as different pointer
sizes, casting integers to pointers, weird architectural pointer types, etc.
Re-worded the description of llvm.readio and llvm.writeio so that it should
be more clear as to why they should be used over regular loads/stores for
I/O.

test:
fld QWORD PTR [%ESP + 4]
fld QWORD PTR [%ESP + 12]
fucomip %ST(1)
fstp %ST(0)
setb %AL

fucompp
** fnstsw

setb %AL
movsx %EAX, %AL

The two marked instructions (which are the ones eliminated) are very bad,
because they serialize execution of the processor. These instructions are
available on the PPRO and later, but since we already use cmov's we aren't
losing any portability.
I retained the old code for the day when we decide we want to support back
to the 386.
