We shall have IA64 as a new experimental backend released with LLVM 1.5

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20671 91177308-0d34-0410-b5e6-96231b3b80d8

remove a bogus optimization.  This only works if there are no globals in the
graph, and the combination of a function that does not reference globals, takes
not arguments and returns no value is pretty rare.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20670 91177308-0d34-0410-b5e6-96231b3b80d8

Rewrite DSAA::getModRefInfo to compute the mapping between caller and callee
to determine mod/ref behavior, instead of creating a *copy* of the caller
graph and inlining the callee graph into the copy.

This speeds up aa-eval on Ptrdist/yacr2 from 109.13s to 3.98s, and gives
identical results.  The speedup is similar on other programs.

Two changes:
  1. Chain to the parent implementation of M/R analysis if we can't find
     any information.  It has some heuristics that often do well.
  2. Do not clear all flags, this can make invalid nodes by turning nodes
     that used to be collapsed into non-collapsed nodes (fixing crashes)
