The softfloat functions float*_is_nan() were badly misnamed,
because they return true only for quiet NaNs, not for all NaNs.
Rename them to float*_is_quiet_nan() to more accurately reflect
what they do.
This change was produced by:
perl -p -i -e 's/_is_nan/_is_quiet_nan/g' $(git grep -l is_nan)
(with the results manually checked.)

Compilation for arm (native or cross) results in this
warning:
fpu/softfloat-native.c: In function ‘float64_round_to_int’:
fpu/softfloat-native.c:387: error: control reaches end of non-void function
float64_round_to_int uses special assembler code for arm
and has no explicit return value.
As there is no obvious reason why arm should need special
code, all fpu related conditionals were removed.
The remaining code is standard (C99) and compiles for arm,
too.

Don't define C99 math functions on OpenSolaris (Solaris 11),
which still ships GCC 3.4.3. This fixes redefinition warnings.

fegetround() and fesetround() are using an int type. Change the type of
float_rounding_mode and floatx80_rounding_precision in the float_status
structure for consistency.
