Eric Fiselier 75627b1a25 [Analysis] Support aligned new/delete functions. ...

Summary:
Clang's __builtin_operator_new/delete was recently taught about the aligned allocation overloads (r328134). This patch makes LLVM aware of them as well.
This allows the compiler to perform certain optimizations including eliding new/delete calls.
