Replace $true assignments to LUT4 inputs by $false #99

Closed tomverbeure closed 6 years ago

tomverbeure commented 6 years ago

This is a fix for an issue that I filed against Yosys.

It finds all LUT4 instances, replaces $true inputs by $false, and rewrites the LUT_INIT to a logical equivalent of the original.
