Sema-based fix for PR2334. The issue is that even if the two sides of
...
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.

Fix a bug in LoopStrengthReduce that caused it to emit IR with
...
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.

Fixed another regression introduced by r51113 caused by some refactoring
...
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.
