[TableGen][DecoderEmitter] Repurpose Filter class (#155065)

There was a lot of confusion about the responsibilities of Filter and
FilterChooser. They created instances of each other and called each
other's methods. Some of the methods had similar names and did similar
things.

This change moves most of the Filter members to FilterChooser and turns
Filter into a supplementary class with short lifetime. FilterChooser
constructs an array of (candidate) Filters, chooses the best performing
one, and applies it to the given set of encodings, creating inferior
FilterChoosers as necessary. The Filter array is then destroyed. All
responsibility for generating the decoder table now lies with
FilterChooser.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

Getting in touch

Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
