Also move the large precompiled methods to their own classes, so that tests that don't support them (e.g. ASMifierTest because the generated code is too big) can still be tested on all instructions. Likewise, duplicate the jdk3.AllInstructions methods in jdk5.AllInstructions, so that tests that don't support jsr/ret (e.g. COMPUTE_FRAMES) can still be tested on all instructions.
