Kaz, if you have some time, could you please gather some CSiBE runtime numbers
for '-mpretend-cmove' and without it?

I've compared the result-size of the CSiBE set and with -mpretend-cmove there's
a total decrease of 948 bytes, with a few opposite cases.

My idea was to obsolete the -mpretend-cmove option, and instead tie its
behavior the new option -mzdcbranch, which generally is supposed to control any
kind of zero-displacement-branch handling.
