softfloat: use GCC builtins to count the leading zeros

Softfloat has its own implementation to count the leading zeros. However
a lot of architectures have either a dedicated instruction or an
optimized to do that. When using GCC >= 3.4, this patch uses GCC builtins...

softfloat: add float*_unordered_{,quiet}() functions

Add float*_unordered() functions to softfloat, matching the softfloat-native
ones. Also add float*_unordered_quiet() functions to match the others
comparison functions.

This allow target-i386/ops_sse.h to be compiled with softfloat....

softfloat-native: add float*_unordered_quiet() functions

Add float*_unordered_quiet() functions to march the softfloat versions.
As FPU status is not tracked with softfloat-native, they don't differ
from the signaling version.

softfloat: rename float*_eq() into float*_eq_quiet()

float*_eq functions have a different semantics than other comparison
functions. Fix that by first renaming float*_quiet() into float*_eq_quiet().

Note that it is purely mechanical, and the behaviour should be unchanged....

softfloat: Add setter function for tininess detection mode

Add a setter function for the underflow tininess detection mode,
in line with the similar functions for other parts of the float status
structure.

softfloat: Add float*_min() and float*_max() functions

Add min and max operations to softfloat. This allows us to implement
propagation of NaNs and handling of negative zero correctly (unlike
the approach of having target helper routines return one of the operands...

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.

softfloat: Resolve type mismatches between declaration and implementation

The original SoftFloat 2.0b library avoided the use of custom integer types
in its public headers. This requires the definitions of int{8,16,32,64} to
match the assumptions in the declarations. This breaks on BeOS R5 and Haiku/x86,...

softfloat: Prepend QEMU-style header with derivation notice

The SoftFloat license requires "prominent notice that the work
is derivative". Having added features like improved 16-bit support
for arm already, add such a notice to the sources.

softfloat-native.[ch] are not under the SoftFloat license...
