4cfc19f34c Remove some unnecessary computations from ANALYZE so that ANALYZE runs with 
fewer CPU cycles.  These changes were spotted while working on the nearby
enhanced-stat1 branch.  So even if enhanced-stat1 is abandoned, that effort
put into it will not have been in vain.

4ccf707c6e Extra steps taken to avoid using low-quality indexes in a query plan. 
This branch accomplishes the same end as the nearby enhanced-stat1 branch,
but with much less change and hence less risk.

307f326ba3 JNI: move the ByteBuffer-using APIs from public to package visibility for the time being because they have UB-inducing possibilities which need to be worked out. Update test code to account for a change in custom FTS5 columntext() impls.

805cd395a9 WASM: various build cleanups and add initial infrastructure for a build which elides the oo1 API and its dependents (worker1 and promiser). Sidebar: an attempt was made to move generation of the build rules to an external script, but the mixed-mode make/script was even less legible than the $(eval) indirection going on in the makefile.
