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)
