[RISCV] Simplify fixup kinds that force relocations

For RELA targets, fixup kinds that force relocations (GOT, TLS, ALIGN,
RELAX, etc) can bypass `applyFixup` and be encoded as
`FirstRelocationKind+i`, as seen in LoongArch. This patch removes
redundant fixup kinds and adopts the `FirstRelocationKind+i` encoding.

The `llvm-mc -show-encoding` output no longer displays descriptive fixup
names, as this information is removed from
`RISCVAsmBackend::getFixupKindInfo`. While a backend hook could be added
to call `llvm::object::getELFRelocationTypeName`, it's unnecessary since
the relocation in `-filetype=obj` output is what truly matters.

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
