In the LIKE optimization, do not analyze the new virtual WHERE clause terms until both have been added, since they are expected to be consecutive and the analysis might add complementary terms. This fixes a problem caused by [44200596aa943963] and discovered by dbsqlfuzz and recorded as case 7e3b5983727d843b910b2d9ab556e4afcd777cfb. (check-in: d35de3ad user: drh tags: trunk)

Do a better job of detecting when a WHERE clause term might be useful to an expression index. Fix for performance regression reported by forum thread e65800d8cb. (check-in: 44200596 user: drh tags: trunk)
