16603ecfcb speedtest1: use the current (or default) vfs->xDelete method to unlink the db. This is specifically necessary when running the opfs vfs in a wasm build of speedtest1.

wrapper functions cli_strcmp() and cli_strncmp() that work correctly even
if the input is a NULL pointer.

805055f734 If a query uses an index where one or more of the columns of the index is 
an expression or a virtual column, and if the corresponding expression is
used elsewhere in the query, then strive to read the value of the expression
out of the index, rather than recomputing it.  This is the
"Indexed Expression Optimizations".

cd0df83c15 Apply considerable acrobatics to get the JS/WASM deliverables building to and loadable from a directory other than the one which contains the app-level code. Requires an only-slightly-leaky abstraction of passing a URL argument when loading sqlite3.js but provides much greater flexibility in where the JS/WASM files are located.

71de8e0241 Considerable wasm/js build cleanups and reworking. Remove wasmfs builds from the end-user deliverables and disable the wasmfs build by default, per /chat discussion, as it doubles our deliverable count for only marginal gain. Attempt to move the sqlite3.js/wasm files into subdirectories but rediscovered that that breaks loading in Worker mode because URI resolution of the wasm files differs depending on whether the main script is loaded from a script tag or a Worker.

6110a5d0ab Put pieces in place for fiddle to support opfs, but more cleanup is required in the sqlite3.js/fiddle connection. bigIntEnabled now defaults to whether the Emscripten's module has bigint enabled. Add wasm-sensible defaults for several SQLITE_ENABLE/OMIT flags in sqlite3-wasm.c.

2897b88f9e The RIGHT JOIN logic added to version 3.39.0 added a new restriction on the 
query flattener which resulted in a performance regression for some queries,
as documented by [forum:/forumpost/96b9e5709cf47cda|forum post 96b9e5709cf47cda].
This change removes that restriction (thus restoring performance) and fixes the
problem that RIGHT JOIN was having in a different way.
