fcf99c532d Reland: [Remarks] Add an LLVM-bitstream-based remark serializer
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.

0294e50fe5 [Remarks] Simplify the creation of remark serializers
Introduce two new functions to create a serializer, and add support for
more combinations to the YAMLStrTabSerializer.

f802102dc4 [Remarks] Introduce a new format: yaml-strtab
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.
