opt_mem_merge: Combine memories for byte enable.
...
The RAMs inferred by GHDL are split into separate instances
for byte enables. This pass recombines memories that have the same
input address (and matching characteristics) allowing a single
BRAM to be used with byte enables.
Work in progress, needs more checks for memory compatibility
Briefly tested to work for microwatt

memory_share: Split off feedback path finding as a separate pass.
...
memory_share is actually three passes in a trenchcoat. Split off the
one that has the least in common with the other two as a separate pass.

Consistent use of 'override' for virtual methods in derived classes.
...
o Not all derived methods were marked 'override', but it is a great
feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
use the plain keyword going forward now that C++11 is established)
