649f05aa24 Switch from llvm::is_trivially_copyable to std::is_trivially_copyable
GCC<5 did not support std::is_trivially_copyable. Now LLVM builds require 5.1
we can migrate to std::is_trivially_copyable.

The Optional.h change made MSVC choke
(https://buildkite.com/llvm-project/premerge-checks/builds/18587#cd1bb616-ffdc-4581-9795-b42c284196de)
so I leave it out for now.

972459e6ed [Bitcode] Move Bitstream to a separate library
This moves Bitcode/Bitstream*, Bitcode/BitCodes.h to Bitstream/.

This is needed to avoid a circular dependency when using the bitstream
code for parsing optimization remarks.

Since Bitcode uses Core for the IR part:

libLLVMRemarks -> Bitcode -> Core

and Core uses libLLVMRemarks to generate remarks (see
IR/RemarkStreamer.cpp):

Core -> libLLVMRemarks

we need to separate the Bitstream and Bitcode part.

For clang-doc, it seems that it doesn't need the whole bitcode layer, so
I updated the CMake to only use the bitstream part.
