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.

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.

This is fairly straight-forward, but was a real nightmare to get just
perfect.  aarg.  :)

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.

Update testcase to illustrate the coalescing problem. The previous one did not work because of a fix in the x86 instruction selector.
