moved of_g to c_gen.of_g_legacy, introduced loxi_globals
as of_g includes loads of legacy data (and a representation that
is increasingly tailored to the c backend only), I've moved it to
c_gen.of_g. In its place, I have created loxi_globals, which gives
access to the list of versions and the IR.
Also loxi reorg: move command line processing to cmdline.py
