773569df86 Switch to use the new interface for the EquivalenceClasses class, and fix 
a bug involving SCC's who have multiple members that are part of an EC.

b3103a3768 Rewrite this class, making the following improvements: 
1. It now actually uses tarjan's algorithm, so it is a efficient inverse
     ackerman's function for union operations, not linear time.
  2. It now stores one copy of the data in the set instead of two.
  3. It now works for elements other than pointers.
  4. It now has a more STL-like interface that exposes iterators instead
     of internal implementation details.

54b0239649 do not bother inlining nullary functions without return values. The only 
effect these calls can have is due to global variables, and these passes
all use the globals graph to capture their effect anyway.  This speeds up
the BU pass very slightly on perlbmk, reducing the number of dsnodes
allocated from 98913 to 96423.

c2d54235d7 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.

57989f2b9a 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.

44cbb1f79f 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)

9802eb4351 Fix a crash that happens when mapping something like this: 
{ short, short }

to
  short

where the second short maps onto the second field of the first struct.  In
this case, the struct index is not aligned, so we should avoid calling
getLink(2), which asserts out.
