This patch fixes the PPC calling convention to handle returns of
_Complex float and _Complex long double, by simply increasing the
number of floating point registers available for return values.

The test case verifies that the correct registers are loaded.

[Linker] Drop support for IR-level extended linking support (archives, etc.).

 - This code is dead, and the "right" way to get this support is to use the
   platform-specific linker-integrated LTO mechanisms, or the forthcoming LLVM
   linker.

Reverting back to the fallback instead of using the 64-bit popcnt instruction as it doesn't exist on all x64 CPU architectures.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172751 91177308-0d34-0410-b5e6-96231b3b80d8
Reverting r171325 & r172363. This was causing a mis-compile on the self-hosted LTO build bots.

Okay, here's how to reproduce the problem:

1) Build a Release (or Release+Asserts) version of clang in the normal way.

2) Using the clang & clang++ binaries from (1), build a Release (or
   Release+Asserts) version of the same sources, but this time enable LTO ---
   specify the `-flto' flag on the command line.

3) Run the ARC migrator tests:

    $ arcmt-test --args -triple x86_64-apple-darwin10 -fsyntax-only -x objective-c++ ./src/tools/clang/test/ARCMT/cxx-rewrite.mm

You'll see that the output isn't correct (the whitespace is off).

The mis-compile is in the function `RewriteBuffer::RemoveText' in the
clang/lib/Rewrite/Core/Rewriter.cpp file. When that function and RewriteRope.cpp
are compiled with LTO and the `arcmt-test' executable is regenerated, you'll see
the error. When those files are not LTO'ed, then the output of the `arcmt-test'
is fine.

It is *really* hard to get a testcase out of this. I'll file a PR with what I
have currently.
