c285b5ff1f Handle one offset with growth case seen in povray. Namely, if we have an offset, 
and the offset lands at a field boundary in the old type, construct a new type,
copying the fields masked by the offset from the old type, and unify with that.

7c2afcfc02 Fix PR681 by using the standard Lengauer and Tarjan algorithm for dominator 
set construction, rather than intersecting various std::sets.  This reduces
the memory usage for the testcase in PR681 from 496 to 26MB of ram on my
darwin system, and reduces the runtime from 32.8 to 0.8 seconds on a
2.5GHz G5.  This also enables future code sharing between Dom and PostDom
now that they share near-identical implementations.

0d3abd353b Be more conservative with our symbolic alias analysis. In particular, 
don't assume that A[1][0] and A[0][i] can't alias.  "i" might be out of
range, or even negative.  This fixes a miscompilation of 188.ammp (which
does bad pointer tricks) with the new CFE.

3cecd3c4cf For PR411: 
This patch is an incremental step towards supporting a flat symbol table.
It de-overloads the intrinsic functions by providing type-specific intrinsics
and arranging for automatically upgrading from the old overloaded name to
the new non-overloaded name. Specifically:
  llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64
  llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64
  llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64
  llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64
  llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64
New code should not use the overloaded intrinsic names. Warnings will be
emitted if they are used.

7f45e655a8 Separate the call graph implementation from its interface. This implements 
the rough idea sketched out in http://nondot.org/sabre/LLVMNotes/CallGraphClass.txt,
allowing new spiffy implementations of the callgraph interface to be built.

Many thanks to Saem Ghani for contributing this!
