[Patch testsuite patch 10/17] Add options for floatN when checking effective target for support

[James Greenhalgh]

Hi,

As Joseph and I discussed in
https://gcc.gnu.org/ml/gcc-patches/2016-11/msg00239.html the
check_effective_target_float<N><x> tests should add any options which the
target requires to enable those float types (add_options_for_float<N><x>.

This patch ensures those options get added, which presently only changes
the testsuite behaviour for the (out-of-tree but submitted for review)
ARM support for _Float16.

Tested on arm-none-linux-gnueabihf with those patches applied, to show that
the _Float16 tests now run.

OK?

Thanks,
James
