The PPC backend was generating random shift counts in this case, due to an
uninitialized variable.

Fold:
seteq ({ short }* cast (int 1 to { short }*), { short }* null)
setlt ({ short }* cast (int 1 to { short }*), { short }* cast (int 2 to { short }*))

to false/true.  These last two commonly occur in the output of compilers that
tag integers, like cozmic's scheme compiler.

This sanitises the world, blows away the specialisations and adds
traits per passmanager type -- seemed most natural.

use virtual registers.  We now allow the first instruction in a block of
terminators to use virtual registers, and update phi elimination to correctly
update livevar when eliminating phi's.  This fixes a problem on a testcase

"All this should do is create what will eventually be the specialised
passmanagers.  Currently, the templates are inheriting them, once the
template specialisations' methods have been absorbed, patches
submitted method by method.  I'll nuke the specialisations and have
the new objects inherit directly from passmanagert, and sanitise the
world of all references to templates.
