Fix that pesky floats in integer regs problem by assigning the f32 type to
...
the correct register class. Also remove the loading of float data into int
regs part of varargs; it will need to be implemented differently later.

going on with copies between floating point and integer register files

Two changes here:
...
1. Instead of copying Local graphs to the BU graphs to start with, use
spliceFrom to do the job (which is constant time in this case). On
176.gcc, this chops off .17s from the bu pass.
2. When building SCC graphs, simplify the logic and use spliceFrom to
do the heavy lifting, instead of cloneInto/delete. This slices
another .14s off 176.gcc.

This replaces the correct but slow code with a more aggressive scc-finder

based approach to find globals and call sites that need to be copied. This
speeds up the BU pass on 176.gcc from 22s back up to 2.3s. Not as good
as 1.5s, but at least it's correct :)
