e542c1c422 Remove spiff. Though it looked good, it was not really as spiffy as it seemed

5613bcc258 Okay, spiff is completely incapable of handling files of nontrivial size. 
Here is a simple minimal program that does what we want.  Instead of taking
minutes to compare mesa's output, and crashing on binary files (like spiff
does), this take < .02s in the common case and doesn't crash.

c71b096672 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.

ff27406cf9 Clean up the Spiff code so that it emits fewer warnings. This 
consists mostly of changing sloppy K&R C code to slightly more
disciplined K&R C code, and doing the usual things to shut gcc up.

7a57647f97 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.
