It should be allowed to take a string table in case all the strings in
the remarks point there, but it shouldn't use it during serialization.

Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across the monorepo.

Add a new serializer, using a binary format based on the LLVM bitstream
format.
This format provides a way to serialize the remarks in two modes:
1) Separate mode: the metadata is separate from the remark entries.
2) Standalone mode: the metadata and the remark entries are in the same
file.
The format contains:
* a meta block: container version, container type, string table,
external file path, remark version
* a remark block: type, remark name, pass name, function name, debug
file, debug line, debug column, hotness, arguments (key, value, debug
file, debug line, debug column)
A string table is required for this format, which will be dumped in the
meta block to be consumed before parsing the remark blocks.
On clang itself, we noticed a size reduction of 13.4x compared to YAML,
and a compile-time reduction of between 1.7% and 3.5% on CTMark.

The default mode is separate, where the metadata is serialized
separately from the remarks.
Another mode is the standalone mode, where the metadata is serialized
before the remarks, on the same stream.

This allows every serializer format to implement metaSerializer() and
return the corresponding meta serializer.

This exposes better support to use a string table with a format through
an actual new remark::Format, called yaml-strtab.
This can now be used with -fsave-optimization-record=yaml-strtab.

Separate the remark serialization to YAML from the LLVM Diagnostics.
This adds a new serialization abstraction: remarks::Serializer. It's
completely independent from lib/IR and it provides an easy way to
replace YAML by providing a new remarks::Serializer.
