Merge commit "Fix tests according to latest yosys and proper gitignore
files".
Make the same changes for 'regression'.

1. Add tests for synth_anlogic command
Now this tests are commented because of:
+ iverilog -o testbench ../testbench.v synth.v ../../common.v
../../../../../techlibs/common/simcells.v
../../../../../techlibs/anlogic/cells_sim.v
../../../../../techlibs/anlogic/cells_sim.v:20: error: Unable to bind
wire/reg/memory `A' in `testbench.uut._09_'
../../../../../techlibs/anlogic/cells_sim.v:20: error: Unable to
elaborate r-value: (INIT)>>(A)
2 error(s) during elaboration.

2. Add 'regression' test

IV frontends
=============

For frontends idea is that you do not do read_verilog but some you are
reading input in different format.
Since most of formats yosys can also read and write you can use plain
verilog write blif for example
and use that as source for this coverage. For liberty files many
examples can be found so that is also in list of tasks
