Rick Altherr 4f74941fcd Avoid combined flags in bitread invocations. 
Combined flags (i.e. -zy) are not universally supported.  Switch to
individual flags (-z -y) in existing scripts to prepare for move to
gflags.

Experiment looking into the CLB PIPs
====================================

None of the CLB PIPs are "real". I.e. all those PIPs are in fact implemented
using other resources. E.g. the PIPs that select which net is routed to which
LUT input pin is implemented by permutating the LUT INIT bits accordingly.
