4c9d4fe24f instead of using a local RetValMap, just use the graph we are cloning into 
for the return node map.

5bd65ee784 two things: 1)evilness reduction patch, reduces the number of instructions hiding in the small jump CC moving code. 2)implement div of small data types by FP DIV (also reduces evilness and should speed things up)

97fc8f85d1 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.

ce471ff361 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.

156e5a6897 Make this method non-const. Making it const causes the const version of 
getIGroup to be called instead of the non-const one.  These two methods
have (??) different behavior, so this change fixes bugs.

1f266b60f8 Change the way that the TD pass inlines graphs. Instead of inlining each 
graph into all of the functions it calls when we visit a graph, change it so
that the graph visitor inlines all of the callers of a graph into the current
graph when it visits it.

While we're at it, inline global information from the GG instead of from each
of the callers.  The GG contains a superset of the info that the callers do
anyway, and this way we only need to do it one time (not one for each caller).

This speeds up the TD pass substantially on several programs, and there is
still room for improvement.  For example, the TD pass used to take 147s
on perlbmk, it now takes 36s.  On povray, we went from about 5s to 1.97s.
134.perl is down from ~1s for Loc+BU+TD to .6s.

The TD pass needs a lot of improvement though, which will occur with later
patches.

cb59ad59dc Build EC's for globals twice. The first is after constructing the initial 
Globals Graph for the local pass, the second is after all of the locals
graphs have been constructed.  This allows for many additional global EC's
to be recognized that weren't before.  This speeds up analysis of programs
like 177.mesa, where it changes DSA from taking 0.712s to 0.4018s.
