7b39686749 If compiled with the -DVDBE_PROFILE=1 option, special code is inserted that 
uses the pentium RDTSC instruction to compute very precise runtimes on all
VDBE opcodes.  (This only works on i586 processors, of course.)  The results
are written into the vdbe_profile.out file for analysis. Hopefully, this
new feature will reveal hot spots that can be optimized to make the VDBE run
faster. (CVS 807)

f5905aa7be NULL values are distinct. A comparison involving a NULL is always false. 
Operations on a NULL value yield a NULL result.  This change makes SQLite
operate more like the SQL spec, but it may break existing applications that
assumed the old behavior.  All the old tests pass but we still need to add
new tests to better verify the new behavior.  Fix for ticket #44. (CVS 589)
