Description: In order to do this, I had to change the generated opcode_metadata.h file to be sensitive to whether NEED_OPCODE_TABLES is defined -- if it is, it defines the functions and data with public linkage, if it isn't it only declares them. That way the file can be included in multiple places without worry about duplicating static data or functions. Also, the pushed/popped functions will now accept any integer opcode argument and return -1 for unknown opcodes. This also changes the command line options for generate_cases.py to write all output files in a single run, and updates Makefile.pre.in accordingly. This halves the time to run the cases generator (since most of the time goes into parsing bytecodes.c). Issue: gh-98831
