da4c7ccc07 The ".testctrl optimizations 0x400000" command disables the generation of 
OP_ReleaseReg opcodes.  OP_ReleaseReg opcodes are usually only generated for
SQLITE_DEBUG builds and are used to verify that registers are descoped
propertly.  But they can get in the way of code understanding when studying
bytecode dumps.  So this new optimization setting is provided to
temporarily turn OP_ReleaseReg opcodes off.
