e70492d0e2 Factor out percentage printing into its own function. Make two changes to
the function: print more precision XX.X% instead of XX%, and cast to ULL
before scaling by 100/1000 to avoid wrap around for large numbers of queries
(such as occur for 253.perlbmk and 176.gcc)

1b9a2aac98 Cache mapping information for a call site after computing it for a mod/ref
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

b7523418b0 Teach steens-aa two things about mod/ref information:
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.

b2dbdc1301 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.
