0433789863 When it is known when preparing a statement that X cannot be NULL, transform the expression (X IS NULL) to integer value 1 instead of 'true'. This is because under some circumstances, "Y IS TRUE" may not be equivalent to "Y IS 1".

c355f6c839 Resolve a parallel build timing issue when building sqlite3.c/h from ext/wasm. For the time being, do not add sqlite3_wasm_extra_init.c to fiddle.wasm because it can cause duplicate definitions of extensions which are already built into the shell (a better resolution for this conflict is pending). No longer add sqlite3_wasm_extra_init.c to speedtest1.wasm because it's useless there.

bf90114867 When flattening a view that is the right operand of a LEFT JOIN, using 
the optimization of check-in [41c27bc0ff1d3135], always insert the
TK_IF_NULL_ROW expression nodes, even for TK_COLUMN expressions, as
the TK_COLUMN might be a column from an outer query and hence still need
to be NULLed out. This fixes the problem described by
[forum:/forumpost/26387ea7ef|forum post 26387ea7ef].
