David Shah ac6cc88db3 memory_bram: Fix multiclock make_transp 
Signed-off-by: David Shah <dave@ds0.me>

whitequark 0c318e7db5 memory_collect: do not truncate 'x from \INIT. 
The semantics of an RTLIL constant that has less bits than its
declared bit width is zero padding. Therefore, if the output of
memory_collect will be used for simulation, truncating 'x from
the end of \INIT will produce incorrect simulation results.

Graham Edgecombe 4fef9689ab memory_bram: Fix initdata bit order after shuffling 
In some cases the memory_bram pass shuffles the order of the bits in a
memory's RD_DATA port. Although the order of the bits in the WR_DATA and
WR_EN ports is changed to match the RD_DATA port, the order of the bits
in the initialization data is not.

This causes reads of initialized memories to return invalid data (until
the initialization data is overwritten).

This commit fixes the bug by shuffling the initdata bits in exactly the
same order as the RD_DATA/WR_DATA/WR_EN bits.

David Shah 3420ae5ca5 memory_bram: Reset make_outreg when growing read ports

Henner Zeller 3aa4484a3c 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)
