[RISCV] Lower vfmv.s.f intrinsics to VFMV_S_F_VL first (#76699)

Currently vfmv.s.f intrinsics are directly selected to their pseudos via
a
tablegen pattern in RISCVInstrInfoVPseudos.td, whereas the other move
instructions (vmv.s.x/vmv.v.x/vmv.v.f etc.) first get lowered to their
corresponding VL SDNode, then get selected from a pattern in
RISCVInstrInfoVVLPatterns.td

This patch brings vfmv.s.f inline with the other move instructions.

Split out from #71501, where we did this to preserve the behaviour of
selecting
vmv_s_x for VFMV_S_F_VL for small enough immediates.

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
