[XRay] A graph Class for the llvm-xray graph Summary: In preparation for graph comparison and filtering, this is a library for representing graphs in LLVM. This will enable easier encapsulation and reuse of graphs in llvm-xray.

[XRay] FDRTraceWriter and FDR Trace Loading Summary: This is the first step in the larger refactoring and reduction of D50441. This step in the process does the following: - Introduces more granular types of `Record`s representing the many kinds of records written/read by the Flight Data Recorder (FDR) mode `Trace` loading function(s). - Introduces an abstract `RecordVisitor` type meant to handle the processing of the various `Record` derived types. This `RecordVisitor` has two implementations in this patch: `RecordInitializer` and `FDRTraceWriter`. - We also introduce a convenience interface for building a collection of `Record` instances called a `LogBuilder`. This allows us to generate sequences of `Record` instances manually (used in unit tests but useful otherwise). - The`FDRTraceWriter` class implements the `RecordVisitor` interface and handles the writing of metadata records to a `raw_ostream`. We demonstrate that in the unit test, we can generate in-memory FDR mode traces using the specific `Record` derived types, which we load through the `loadTrace(...)` function yielding valid `Trace` objects. This patch introduces the required types and concepts for us to start replacing the logic implemented in the `loadFDRLog` function to use the more granular types. In subsequent patches, we will introduce more visitor implementations which isolate the verification, printing, indexing, production/consumption, and finally the conversion of the FDR mode logs. The overarching goal of these changes is to make handling FDR mode logs better tested, more understandable, more extensible, and more systematic. This will also allow us to better represent the execution trace, as we improve the fidelity of the events we represent in an XRay `Trace` object, which we intend to do after FDR mode log processing is in better shape.

[XRay] Add a BlockIndexer visitor for FDR Records. Summary: This change adds a `BlockIndexer` type which maintains pointers to records that belong to the same process+thread pairs. The indexing happens with order of appearance of records as they are visited. This version of the indexer currently only supports FDR version 3 logs, which contain `BufferExtent` records. We will add support for v2 and v1 logs in follow-up patches. This is another part of D50441.

[XRay] Add a BlockVerifier visitor for FDR Records Summary: This patch implements a `BlockVerifier` type which enforces the invariants of the log structure of FDR mode logs on a per-block basis. This ensures that the data we encounter from an FDR mode log semantically correct (i.e. that records follow the documented "grammar" for FDR mode log records). This is another part of the refactoring of D50441. This is a slightly modified version of rL341628, avoiding the `std::tuple<...>` constructor that is not constexpr in C++11.

[XRay] FDR Record Producer/Consumer Implementation Summary: This patch defines two new base types called `RecordProducer` and `RecordConsumer` which have default implementations for convenience (particularly for testing). A `RecordProducer` implementation has one member function called `produce()` which serves as a factory constructor for `Record` instances. This code exercises the `RecordInitializer` code path in the implementation for `FileBasedRecordProducer`. A `RecordConsumer` has a single member function called `consume(...)` which, as the name implies, consumes instances of `std::unique_ptr<Record>`. We have two implementations, one of which is used in the test to generate a vector of `std::unique_ptr<Record>` similar to how the `LogBuilder` implementation works. We introduce a test in `FDRProducerConsumerTest` which ensures that records we write through the `FDRTraceWriter` can be loaded by the `FileBasedRecordProducer`. The record(s) loaded this way are written again through the `FDRTraceWriter` into a separate string, which we then compare. This ensures that the read-in bytes to create the `Record` instances in memory can be replicated when written out through the `FDRTraceWriter`. This change depends on D51210 and is part of the refactoring of D50441 into smaller, more focused changes.

[XRay] Add a RecordPrinter visitor for FDR Records Summary: This change adds a `RecordPrinter` type which does some basic text serialization of the FDR record instances. This is one component of the tool we're building to dump the records from an FDR mode log as-is. This is a small part of D50441.

[XRay] Add the `llvm-xray fdr-dump` implementation Summary: In this change, we implement a `BlockPrinter` which orders records in a Block that's been indexed by the `BlockIndexer`. This is used in the `llvm-xray fdr-dump` tool which ties together the various types and utilities we've been working on, to allow for inspection of XRay FDR mode traces both with and without verification.
