7142db28a8 HeAP: Make HeAP placer optional 
A CMake option 'BUILD_HEAP' (default on) configures building of the
HeAP placer and the associated Eigen3 dependency.

Default for the iCE40 is SA placer, with --heap-placer to use HeAP

Default for the ECP5 is HeAP placer, as SA placer can take 1hr+ for
large ECP5 designs and HeAP tends to give better QoR. --sa-placer can
be used to use SA instead, and auto-fallback to SA if HeAP not built.

d6fd0e7e5b common/placer1: In random pick, only use grid if there is more than 64 BELs 
If you have a large grid and very few BELs of a given type, picking a
random grid location yields very little odds of finding a BEL of that
type.

So for those, just put all of them at (0,0) and do a true random pick.

d03291eeb1 gui: improved FPGAViewWidget::paintGL() performance 
Profiling revealed that memcpy() in QOpenGLBuffer::allocate() had been taking
the most time during paintGL() calls. I've been able to take the CPU usage
down to about 1/4 of its previous values by caching elements in VBOs and
updating them only after subsequent calls to renderGraphicElement().
