autoconf: Fix soname for libLLVM-Major.Minor.so (2nd try)

We were using libLLVM-Major.Minor.Patch.so for the soname, but we
need the soname to stay consistent for all Major.Minor.* releases
otherwise operating system distributors  will need to rebuild all
packages that link with LLVM every time there is a new point release.

This patch also reverses the compatibility symlink, so
libLLVM-Major.Minor.Patch.so is now a symlink that points
to libLLVM-Major-Minor.so.

[PowerPC] On PPC32, 128-bit shifts might be runtime calls

The counter-loops formation pass needs to know what operations might be
function calls (because they can't appear in counter-based loops). On PPC32,
128-bit shifts might be runtime calls (even though you can't use __int128 on
PPC32, it seems that SROA might form them).

Fixes PR19709.

autoconf: Fix libLLVM-Major-Minor-Patch.so symlink

The symlink needs to point to a relative path, so we don't break
building in a chroot.
