the function: print more precision XX.X% instead of XX%, and cast to ULL

query.  If the next mod/ref query happens to be for the same call site
(which is extremely likely), use the cache instead of recomputing the
callee/caller mapping.  This makes -aa-eval ***MUCH*** faster with
ds-aa

  1. If memory never escapes the program, it cannot be mod/ref'd by external
     functions.
  2. If memory is global never mod/ref'd in the program, it cannot be mod/ref'd
     by any call.

before moving on to the next call site.  This will be a more efficient way
to compute the mod/ref set for AA implementations like DSA.

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
being generated.  Once that is solved, varargs will be done.

  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.

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 :)
