abb59a3c21 Instead of setting up the CFG edges at selectiondag construction time, set
them up after the code has been emitted.  This allows targets to select one
mbb as multiple mbb's as needed.

02a4d3bd9b Fix a bug that andrew noticed where we do not correctly sign/zero extend
returned integer values all of the way to 64-bits (we only did it to 32-bits
leaving the top bits undefined).  This causes problems for targets like alpha
whose ABI's define the top bits too.

5ceaf630ab Fix a major problem with global variable initializers. This could cause
us to have stuff pointing to the null pointer, which makes no sense
(the null ptr is an ssa value, not the null object)

3a88055932 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)

b84076a278 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

02275101be 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.

bbec058833 Interchange this loop so that we test all pointers against one call site
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.
