Bug 963434 - Remove jsopcode.tbl and jsoplengen.cpp in favor of a higher-order macro, and make JSOP_*_LENGTH into C++ constant variables. This will make the build process simpler, and it likely eliminates a needs-CLOBBER situation encountered while landing bug 948583. Particular thanks to r=jorendorff for the fast review here (given any change at all to jsopcode.tbl would bitrot this), DONTBUILD because already landed with wrong bug number
