bb98fe42c5 softfloat: Drop [s]bits{8, 16, 32, 64} types in favor of [u]int{8, 16, 32, 64}_t 
They are defined with the same semantics as the POSIX types,
so prefer those for consistency. Suggested by Peter Maydell.

185698715d softfloat: Rename float*_is_nan() functions to float*_is_quiet_nan() 
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.)

bc4347b883 arm host: fix compiler warning 
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.

According to $GCC/gcc/config/rs6000/rs6000-c.c _ARCH_PPC is the

PowerPC, on 64bit platforms _ARCH_PPC64 will be also defined.
