by erasing the soft-float target feature if the rest of the front
end added it because of defaults or the soft float option.
Add some testing for some of the targets that implement this hack.

This makes sure that the front end is specific about what they're expecting
the backend to produce. Update a FIXME with the idea that the target-features
could be more precise using backend knowledge.

the target-cpu, if different from the triple's cpu, and
target-features as they're written that are passed down from the
driver.
Together with LLVM r232885 this should allow the LTO'ing of binaries
that contain modules compiled with different code generation options
on a subset of architectures with full backend support (x86, powerpc,
aarch64).
