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

(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

     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.

4da120e5d6 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 :)

e3f1d8a525 Totally gut mergeInGraph. There is absolutely no reason to be merging 
global roots in from callees to callers.  The BU graphs do not have accurate
globals information and all of the clients know it.  Instead, just make sure
the GG is up-to-date, and they will be perfectly satiated.

This speeds up the BU pass on 176.gcc from 5.5s to 1.5s, and Loc+BU+TD
from 7s to 2.7s.

1e9d1475bc Several changes here: 
1. Increase max node size from 64->256 to avoid collapsing an important
   structure in 181.mcf
2. If we have multiple calls to an indirect call node with an indirect
   callee, fold these call nodes together, to avoid DSA turning apoc into
   a flaming fireball of death when analyzing 176.gcc.
  With this change, 176.gcc now takes ~7s to analyze for loc+bu+td, with
  5.7s of that in the BU pass.

9308a35532 When making a clone of a DSGraph from the BU pass, make sure to remember that 
this clone is supposed to be used for *ALL* of the functions in the SCC.

This fixes the memory explosion problem the TD pass was having, reducing the
memory growth from 24MB -> 3.5MB on povray and 270MB ->8.3MB on perlbmk!
This obviously also speeds up the TD pass *a lot*.

3bc703ba22 Don't use operator[], use the new method instead, which is faster. This speeds

275b301740 Enhance the TD pass to build composite graphs when we have indirect call 
sites that target multiple callees.  If we have a function table, for
example, with N callees, and M callers call through it, we used to have
to perform O(M*N) graph inlinings.  Now we perform O(M+N) inlinings.

This speeds up the td pass on perlbmk from 36.26s to 25.75s.

355ad1f3af Remove a bunch of cruft and dead code for handling the case when types were 
defined in function constant pools.  The assembler grammar has long
disallowed functions from having constant pools, so all of this stuff is
dead.

This makes it an immediate error for functions to refer to nonexisting
types, fixing Regression/Verifier/2005-03-21-UndefinedTypeReference.ll.

Before, references to non-existing types in functions would only be
detected when the subsequent function was parsed, due to the call to
"ResolveTypes".  "ResolveTypes" has not resolved any types for a long time,
instead it emitted an error message if no resolved types are left.  Since
the only caller of this method is in the module code, just inline it.
