Removed all of the CompilationMode stuff because it was cluttering the code too much.

 Decided that if you are going to write L1 programs by hand, you just have to put the stack adjustments in at the start of the function and before returns. This works good because L1 is supposed to be very much like x86. L2 already generates the stack adjustments.

 Fixed up all the handwritten L1 test files.
