[XRay] Implement `llvm-xray extract`, start of the llvm-xray tool Usage: llvm-xray extract <object file> [-o <filename or '-'>] The tool gets the XRay instrumentation map from an object file and turns it into YAML. We first support ELF64 sleds on x86_64 binaries, with provision for supporting other supported platforms and formats later. This is the first of a many-part change to fully implement the `llvm-xray` tool. We also define a subcommand registration and dispatch mechanism to be used by other further subcommand implementations for llvm-xray.

[XRay] Implement `llvm-xray convert` -- trace file conversion This is the second part of a multi-part change to define additional subcommands to the `llvm-xray` tool. This change defines a conversion subcommand to take XRay log files, and turns them from one format to another (binary or YAML). This currently only supports the first version of the log file format, defined in the compiler-rt runtime. Depends on D21987.

[XRay] Define the library for XRay trace logs Summary: In this change we move the definition of the log reading routines from the tools directory in LLVM to {include/llvm,lib}/XRay. We improve the documentation a little bit for the publicly accessible headers, and adjust the top-matter. This also leads to some refactoring and cleanup in the tooling code. In particular, we do the following: - Rename the class from LogReader to Trace, as it better represents the logical set of records as opposed to a log. - Use file type detection instead of asking the user to say what format the input file is. This allows us to keep the interface simple and encapsulate the logic of loading the data appropriately. In future changes we increase the API surface and write dedicated unit tests for the XRay library. Depends on D24376.

[XRay] Implement the `llvm-xray account` subcommand Summary: This is the third of a multi-part change to implement subcommands for the `llvm-xray` tool. Here we define the `account` subcommand which does simple function call accounting, generating basic statistics on function calls we find in an XRay log/trace. We support text output and csv output for this subcommand. This change also supports sorting, summing, and filtering the top N results. Part of this tool will later be turned into a library that could be used for basic function call accounting. Depends on D24376.

[XRay][tools] Function call stack based analysis tooling for XRay traces Second try after fixing a code san problem with iterator reference types. This change introduces a subcommand to the llvm-xray tool called "stacks" which allows for analysing XRay traces provided as inputs and accounting time to stacks instead of just individual functions. This gives us a more precise view of where in a program the latency is actually attributed. The tool uses a trie data structure to keep track of the caller-callee relationships as we process the XRay traces. In particular, we keep track of the function call stack as we enter functions. While we're doing this we're adding nodes in a trie and indicating a "calls" relatinship between the caller (current top of the stack) and the callee (the new top of the stack). When we push function ids onto the stack, we keep track of the timestamp (TSC) for the enter event. When exiting functions, we are able to account the duration by getting the difference between the timestamp of the exit event and the corresponding entry event in the stack. This works even if we somehow miss the exit events for intermediary functions (i.e. if the exit event is not cleanly associated with the enter event at the top of the stack). The output of the tool currently provides just the top N leaf functions that contribute the most latency, and the top N stacks that have the most frequency. In the future we can provide more sophisticated query mechanisms and potentially an export to database feature to make offline analysis of the stack traces possible with existing tools.
