[RISCV] Remove legacy TA/TU pseudo distinction for VID

This is a follow on to D152740. The focus of this patch is on actually removing the old TA (unsuffixed) version. I realized we already had plumbing for combined TA/TU pseudos - used by some of the ternary instructions. As such, we can go ahead and fully remove the old TA, and rename the _TU variant to be unsuffixed. (The rename must happen in this patch for the table structure to work out as expected.)

The scheduling difference comes from an omission in D152740. If we selected a _MASK variant - either from manual ISEL or instrincs - we were going through doPeepholeMaskedRVV and still getting the TA variant. The use of the IsCombined flag in the MaskedPseudo table causes us to use the TU (now unsuffixed) variant instead.

The LLVM Compiler Infrastructure

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, or #llvm IRC channel on OFTC.

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