  softfloat: add float128_is_{normal,denormal}

Needed on s390x, to test for the data class of a number. So it will
gain soon a user.

A number is considered normal if the exponent is neither 0 nor all 1's.
That can be checked by adding 1 to the exponent, and comparing against
>= 2 after dropping an eventual overflow into the sign bit.

While at it, convert the other floatXX_is_normal functions to use a
similar, less error prone calculation, as suggested by Richard H.

  softfloat: Implement float128_to_uint32

Handling it just like float128_to_uint32_round_to_zero, that hopefully
is free of bugs :)

Documentation basically copied from float128_to_uint64

We've just added f128_to_ui32 and we missed out the f128_to_ui64 tests
last time.

  softfloat: Support float_round_to_odd more places

Previously this was only supported for roundAndPackFloat64.

New support in round_canonical, round_to_int, float128_round_to_int,
roundAndPackFloat32, roundAndPackInt32, roundAndPackInt64,
roundAndPackUint64.  This does not include any of the floatx80 routines,
as we do not have users for that rounding mode there.

  tests/Makefile.include: test all rounding modes of softfloat

We missed a bug in a recent patch as we were not testing all the
rounding modes for all operations. However enabling all rounding modes
for mulAdd does slow down the already slowest test and doesn't really
buy us much additional coverage so lets allow the default test flags
to be overridden.
