* Add support for uniquing strings in the remark streamer and emitting the string table in the remarks section.
* Add parsing support for the string table in the RemarkParser.
From this remark:
```
--- !Missed
Pass: inline
Name: NoDefinition
DebugLoc: { File: 'test-suite/SingleSource/UnitTests/2002-04-17-PrintfChar.c',
Line: 7, Column: 3 }
Function: printArgsNoRet
Args:
- Callee: printf
- String: ' will not be inlined into '
- Caller: printArgsNoRet
DebugLoc: { File: 'test-suite/SingleSource/UnitTests/2002-04-17-PrintfChar.c',
Line: 6, Column: 0 }
- String: ' because its definition is unavailable'
...
```
to:
```
--- !Missed
Pass: 0
Name: 1
DebugLoc: { File: 3, Line: 7, Column: 3 }
Function: 2
Args:
- Callee: 4
- String: 5
- Caller: 2
DebugLoc: { File: 3, Line: 6, Column: 0 }
- String: 6
...
```
And the string table in the .remarks/__remarks section containing:
```
inline\0NoDefinition\0printArgsNoRet\0
test-suite/SingleSource/UnitTests/2002-04-17-PrintfChar.c\0printf\0
will not be inlined into \0 because its definition is unavailable\0
```
This is mostly supposed to be used for testing purposes, but it gives us
a 2x reduction in the remark size, and is an incremental change for the
updates to the remarks file format.

This adds a Remark class that allows us to share code when working with
remarks.
The C API has been updated to reflect this. Instead of the parser
generating C structs, it's now using a C++ object that is used through
opaque pointers in C. This gives us much more flexibility on what
changes we can make to the internal state of the object and interacts
much better with scenarios where the library is used through dlopen.
* C API updates:
* move from C structs to opaque pointers and functions
* the remark type is now an enum instead of a string
* unit tests updates:
* use mostly the C++ API
* keep one test for the C API
* rename to YAMLRemarksParsingTest
* a typo was fixed: AnalysisFPCompute -> AnalysisFPCommute.
* a new error message was added: "expected a remark tag."
* llvm-opt-report has been updated to use the C++ parser instead of the
C API

Rename it to reflect that it's parsing YAML remarks.

Getting rid of the name "optimization remarks" for anything that
involves handling remarks on the client side.
It's safer to do this now, before we get stuck with that name in all the
APIs and public interfaces we decide to export to users in the future.
This renames llvm/tools/opt-remarks to llvm/tools/remarks-shlib, and now
generates `libRemarks.dylib` instead of `libOptRemarks.dylib`.
