Benjamin Kramer adcd026838 Make llvm::StringRef to std::string conversions explicit.
This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Francis Visoiu Mistrih 4506afe3ca [Remarks] Allow empty temporary remark files
When parsing bitstream remarks, allow external remark files to be
empty, which means there are no remarks to be parsed.

In the same way, dsymutil should not produce a remark file.

Francis Visoiu Mistrih 684605ec0e [Remarks] Add support for prepending a path to external files
This helps with testing and debugging for paths that are assumed
absolute.

It also uses a FileError to provide the file path it's trying to open.

Francis Visoiu Mistrih a85d9ef11a [Remarks] Add parser for bitstream remarks
The bitstream remark serializer landed in r367372.

This adds a bitstream remark parser that parser bitstream remark files
to llvm::remarks::Remark objects through the RemarkParser interface.

A few interesting things to point out:

* There are parsing helpers to parse the different types of blocks
* The main parsing helper allows us to parse remark metadata and open an
external file containing the encoded remarks
* This adds a dependency from the Remarks library to the BitstreamReader
library
* The testing strategy is to create a remark entry through YAML, parse
it, serialize it to bitstream, parse that back and compare the objects.
* There are close to no tests for malformed bitstream remarks, due to
the lack of textual format for the bitstream format.
* This adds a new C API for parsing bitstream remarks:
LLVMRemarkParserCreateBitstream.
* This bumps the REMARKS_API_VERSION to 1.
