[dev.cc] cmd/internal/obj, cmd/internal/gc, new6g: reconvert

Browse source 
Reconvert using rsc.io/c2go rev 27b3f59.

Changes to converter:
 - fatal does not return, so no fallthrough after fatal in switch
 - many more function results and variables identified as bool
 - simplification of negated boolean expressions
