6833ffe8b8 For PR950: 
Make necessary changes to support DIV -> [SUF]Div. This changes llvm to
have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.

This patch implements the first increment for the Signless Types feature.
All changes pertain to removing the ConstantSInt and ConstantUInt classes
in favor of just using ConstantInt.

f0c3081939 Teach globalsmodref-aa to track scalar pointer global variables which point 
to unaliased allocations.  Use this information to disambiguate pointers loaded
from them.  This is a very common case, so it's worthwhile to handle efficiently.

This implements Analysis/GlobalsModRef/indirect-global.ll

a5bb9b49d3 Do not rely on std::sort and std::erase to get list of unique

9781d44b6e Make Loop::getExitBlocks significantly faster for large loops. Instead of 
pounding on Loop::contains (which is O(n) in the size of the loop), use a
sorted vector, which is O(log(N)) for each query.  This speeds up Duraid's
horrible testcase from ~72s to ~31s in a debug build.

a21497f1b8 Speed up Loop::isLCSSAForm by using a binary search and single-entry cache. 
This reduces LCSSA pass time from 1.5s to 0.96s when run on eon in release+asserts mode.

e5e2e8d917 Change the callgraph representation to store the callsite along with the 
target CG node.  This allows the inliner to properly update the callgraph
when using the pruning inliner.  The pruning inliner may not copy over all
call sites from a callee to a caller, so the edges corresponding to those
call sites should not be copied over either.

This fixes PR827 and Transforms/Inline/2006-07-12-InlinePruneCGUpdate.ll

a3a29d82b6 Don't implement AliasSetTracker::remove in terms of deleteValue. deleteValue 
causes the pointer to be removed from the underlying alias analysis
implementation as well.  This impl of remove is also significantly faster than
the old one.  This fixes:

f0ecdbe7ef Do partial inlining in BU. This resolves more call sites. Also add options to merge in globals during recursion and to back annotate DSNodes when function pointers are resolved. This makes PA work for a whole lot more things (unresolved call sites being what has been killing various DSA based passes)
