drh 72d03a646c Change the SQLITE_Stat34 bit of the optimization test-control so that it 
prevents STAT4 data from being used but allows it to be loaded into the
Index objects.  This permits STAT4 to be turned on and off on a per-statement
basis.

drh 6ccbd2787b Further improvements to bytecode branch testing. Fix cases where the 
macros said a branch could not be taken when in fact it could be.  Alter
some window function branch coverage macros to indicate that comparison
operands cannot be NULL.

FossilOrigin-Name: 76e42b7071a71137c0da4f10db4e653ae94a89b56e95cd3f036bff08c9500d08

drh 7083a487ad Enhancements and improved documentation to the byte-code branch coverage 
testing logic.  Provide new macros that allow the code to specify that
some branch instructions can never take the NULL path and that the OP_Jump
opcode is only interested in equal/not-equal.  The
SQLITE_TESTCTRL_VDBE_COVERAGE file control callback now works slightly
differently (it provides the callback with a bitmask of the branch action,
rather than an integer).
