[VPlan] Move initial skeleton construction earlier (NFC). (#150848)

Split up the not clearly named prepareForVectorization transform into
buildVPlan0, which adds the vector preheader, middle and scalar
preheader blocks, as well as the canonical induction recipes and sets
the trip count. The new transform is run directly after building the
plain CFG VPlan initially.

The remaining code handling early exits and adding the branch in the
middle block is renamed to handleEarlyExitsAndAddMiddleCheck and still
runs at the original position.

With the code movement, we only have to add the skeleton once to the
initial VPlan, and cloning will take care of the rest. It will also
enable moving other construction steps to work directly on VPlan0, like
adding resume phis.

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.
