[Bug translator/11246] New: Add better control over caching

We now have several things that are stored in cache:
1. The script's module, stap.c and stap.ko
2. The common autoconf result, stapconf.h
3. The tracepoint query modules, tracequery.ko
4. The @cast w/ header modules, typequery_umod.so and typequery_kmod.ko
We have a single session variable, use_cache, which controls all of these. When
someone uses the -k or -m options, we end up disabling all of the cache. We
really only need to disable #1 in that case, and it would be nice to still
benefit from the rest of the caching.
While we're at it, we could use some command-line options to control the cache
for debugging. A few ideas:
--disable-cache : turn off all caching
--clean-cache : clean up stale entries and then quit
--poison-cache : force regeneration of items that would have hit the cache
