description:
Refactored njs_vmcode_interpreter() for performance.
1) opcodes are rewritten using switch table.
2) often-used opcodes are prioritized and
inlined.
3) similar opcodes are combined into unified
handlers.
4) njs_vmcode_interpreter() return NJS_OK on
success. NJS_STOP return code is removed.
