Follow up to LLVM-side change to allow conversion to hot/cold hinted operator new, not yet standard but supported by open source tcmalloc. The LLVM change in a35206d78280e0ebcf48cd21bc5fff5c3b9c73fa added the necessary support to recognize these as library functions, and we subsequently found that a clang-side change is needed to give them builtin/nobuiltin attributes as appropriate so they have consistent removeability. Based on discussion with Richard Smith, converted the parameter type to a reserved identifier (39f7b48671dae5fbe3afc49f33f50c2b6340bb89) and added support in this patch to recognize it in clang.

The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
