[RISCV] Improve Errors for X1/X5/X1X5 Reg Classes (#126184)

LLVM has functionality for producing a register-class-specific error
message in the assembly parser, rather than just emitting the generic
"invalid operand for instruction" error.

This starts the gradual adoption of this functionality for RISC-V, with
some lesser-used shadow-stack register classes:
- GPRX1 (only contains `ra`)
- GPRX5 (only contains `t0`)
- GPRX1X5 (only contains `ra` and `t0`)

LLVM is reasonably conservative about when these errors are used, in
particular you have to have all the features for the relevant mnemonic
enabled before it will do, hence the test updates.

This also merges a pair of almost identical rv32/rv64 test files into a
single file with one run line.

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.
