Move part of SSE 1 & 2 compare, shuffle and unpack instructions closely. Preparing them for refactoring and to the addition of their AVX forms

Add AVX regular (non-aliased ones) and,or,xor,andn packed instructions. They are already tested in the MC framework, no test needed

Split the code for materializing a value out of
SelectionDAGBuilder::getValue into a helper function, so that it can
be used in other ways. Add a new getNonRegisterValue function which
uses it, for use in code which doesn't want a CopyFromReg even
when FuncMap.ValueMap already has an entry for it.

This allows the fast regiser allocator to remove redundant 
register moves.
Update a set of tests that depend on the register allocator
to be linear scan.

I was trying to do some refactoring on the copyRegToReg, but this is realyl a work in progress and not generally useful yet.

use sharing map. The reconcileNewOffset logic already forces a
separate use if the kinds differ, so incorporating the kind in the
key means we can track more sharing opportunities.

More sharing means fewer total uses to track, which means smaller
problem sizes, which means the conservative throttles don't kick
in as often.
