Martin Storsjö 36cf1e7d0e Revert "[AggressiveInstCombine] Generalize foldGuardedRotateToFunnelShift to generic funnel shifts" 
This reverts commit 59b22e495c.

That commit broke building for ARM and AArch64, reproducible like this:

$ cat apedec-reduced.c
a;
b(e) {
  int c;
  unsigned d = f();
  c = d >> 32 - e;
  return c;
}
g() {
  int h = i();
  if (a)
    h = h << a | b(a);
  return h;
}
$ clang -target aarch64-linux-gnu -w -c -O3 apedec-reduced.c
clang: ../lib/Transforms/InstCombine/InstructionCombining.cpp:3656: bool llvm::InstCombinerImpl::run(): Assertion `DT.dominates(BB, UserParent) && "Dominance relation broken?"' failed.

Same thing for e.g. an armv7-linux-gnueabihf target.

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.
