  fp-bench: fix update_random_ops

The second test in the branches is wrong; fix while converting
to a switch statement, which is easier to get right.

  fp-bench: remove wrong exponent raise in fill_random

At this point random_ops[] only contains normals, so there's
no need to do anything to them. In fact, raising the exponent
here can make the output !normal, which is precisely
what the comment says we want to avoid.

  tests/fp/platform.h: include config-host.h

We get HOST_WORDS_BIGENDIAN from config-host.h, but the include
is missing. Fix it.

This fixes `make check-softfloat' on big endian hosts.

  Log Message:
  -----------
  softfloat: enforce softfloat if the host's FMA is broken

The added branch to the FMA ops is marked as unlikely and therefore
its impact on performance (measured with fp-bench) is within noise range
when measured on an Intel(R) Xeon(R) Gold 6142 CPU @ 2.60GHz.

  include/fpu/softfloat: Fix compilation with Clang on s390x

Clang v7.0.1 does not like the __int128 variable type for inline
assembly on s390x:

In file included from fpu/softfloat.c:97:
include/fpu/softfloat-macros.h:647:9: error: inline asm error:
 This value type register class is not natively supported!
    asm("dlgr %0, %1" : "+r"(n) : "r"(d));
  ^

Disable this code part there now when compiling with Clang, so that
the generic code gets used instead.

  tests/Makefile: add floating point tests

Wire up test/fp-test into the main testing Makefile. Currently we skip
some of the extF80 and f128 related tests. Once we re-factor and fix
these tests the plumbing should get simpler.
