Simon Pilgrim 295b5dea73 [X86][SSE] Support variable-index float/double vector insertion on SSE41+ targets (PR47924) 
Extends D95779 to permit insertion into float/doubles vectors while avoiding a lot of aliased memory traffic.

The scalar value is already on the simd unit, so we only need to transfer and splat the index value, then perform the select.

SSE4 codegen is a little bulky due to the tied register requirements of (non-VEX) BLENDPS/PD but the extra moves are cheap so shouldn't be an actual problem.

The LLVM Compiler Infrastructure
================================

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
