Joseph Huber 2a65d0388c [libc] Add support for creating wrapper headers for offloading in clang This is an alternate approach to the patches proposed in D153897 and D153794. Rather than exporting a single header that can be included on the GPU in all circumstances, this patch chooses to instead generate a separate set of headers that only provides the declarations. This can then be used by external tooling to set up what's on the GPU. This leaves room for header hacks for offloading languages without needing to worry about the `libc` implementation. Currently this generates a set of headers that only contain the declarations. These will then be installed to a new clang resource directory called `llvm_libc_wrappers/` which will house the shim code. We can then automaticlaly include this from `clang` when offloading to wrap around the headers while specifying what's on the GPU.

The LLVM libc header generation system

LLVM libc uses a header generation scheme to generate public as well as internal header files. This directory contains the implementation of the header generator which drives this header generation scheme.
