testsuite: Fix up ext-floating{3,12}.C on i686-linux
These tests FAIL for quite a while on i686-linux since July last year,
likely r14-2628 . Since that patch gcc claims _Float16 and __bf16
support even without -msse2 because some functions could be using
target attribute.
Later r14-2691 added -msse2 to add_options_for_float16, but didn't do that
for bfloat16, plus ext-floating{3,12}.C tests need the added dg-add-options,
so that float16 and bfloat16 effective targets match the
__STDCPP_FLOAT16_T__
or __STDCPP_BFLOAT16_T__ macros.

on the latter and changes nothing on the former.
