the condidtional have compatible types, they are not necessarily the 
same type.  Therefore, we cast to the composite type.  As a hack, for 
the moment we assume that the composite type is the type of the 
left-hand expression; this isn't correct, but it's good enough for most 
purposes.

Partitioned BugTypeCachedLocation::isCached() into two methods: one that accepts and ExplodedNode, and the other that accepts a ProgramPoint.  The default behavior is to cache bug reports by the
location they occur (the end node).  Subclasses can override this behavior by providing a different ProgramPoint.

Also, use SCEV to determine the trip count of the loop, which is more powerful
and accurate that Loop::getTripCount.

Instead, fix getIndexedType to not follow pointer types, as
PointerType is a subclass of CompositeType.

use-before-def. The problem comes up in code with multiple PHIs where
one PHI is being rewritten in terms of the other, but the other needs
to be casted first. LLVM rules requre the cast instruction to be
inserted after any PHI instructions, but when instructions were
inserted to replace the second PHI value with a function of the first,
they were ended up going before the cast instruction. Avoid this
problem by remembering the location of the cast instruction, when one
is needed, and inserting the expansion of the new value after it.

This fixes a bug that surfaced in 255.vortex on x86-64 when
instcombine was removed from the middle of the loop optimization
passes.

in Sema::CheckFunctionCall:

  http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20080512/005706.html
  
The bug was that the logic from the helper methods used by CheckFunctionCall
were being inverted (a subtle bug).  This would cause the parser to discard
any valid AST nodes involving several builtins (see patch).

This removes the last regression failure I'm seeing in the test suite: Analysis-Apple/NoReturn.
