Siva Chandra Reddy a32af8252f [libc] Add a tool called WrapperGen.
This tool will be used to generate C wrappers for the C++ LLVM libc
implementations. This change does not hook this tool up to anything yet.
However, it can be useful for cases where one does not want to run the
objcopy step (to insert the C symbol in the object file) but can make use
of LTO to eliminate the cost of the additional wrapper call. This can be
relevant for certain downstream platforms. If this tool can benefit other
libc platforms in general, then it can be integrated into the build system
with options to use or not use the wrappers. An example of such a
platform is CUDA.

Siva Chandra Reddy 59f17a7d4f [libc][NFC] Move tablegen indexer class into a util library of its own.
This class is currently used by two tools: HdrGen and PrototypeTestGen.
We will be adding more tools based on this class so it is convenient to
keep it in a util library of its own.
