v37 POLXY() in no longer working the same

[PropGit]

POLXY() in v37 is reporting different values than an v36. This was reported for Propeller Tool but as it relates to the P2 compiler changes.

I verified that the Spin2 Interpreter code for POLXY(), ROTXY(), and XYPOL() was changed in v37. @ChipGracey will need to review and fix.

POLXY() is definitely affected; not sure if ROTXY() or XYPOL() is adversely affected or not.

Sorry about this. I had forgotten to use a #immediate in the interpreter when comparing which instruction we were executing. I've fixed this, but need to push it.

In the spin2_interpreter.spin2 file:

	cmp	pa,bc_polxy

...needs to become...

	cmp	pa,#bc_polxy

That will fix this problem.
