As before, not every platform supports LTO. Make sure the platform
we're targeting is one that supports it (regardless of the *host*
platform).
llvm-svn: 311488
Not all targets will use -plugin with -flto. Pick a fixed target so
this works regardless of the default target (regardless of host OS,
the toolchain should be picking the correct LTO plugin for a target
that supports it).

Summary:
Relanding https://reviews.llvm.org/D35739 which was reverted because
it broke the tests on non-Linux. The tests have been fixed to be
platform agnostic, and additional tests have been added to make sure
that the plugin has the correct extension on each platform
(%pluginext doesn't work in CHECK lines).
