This only happens for a "back" value of 0 which is invalid anyway,
but lcldec does not properly validate input.
Also extend the documentation to specify valid values.

Firstly, this test never worked as intended, always reporting
success. Secondly, bswap is available from 486 onward and can
thus be assumed present.

With these changes, gcc 4.5 and later recognise it as a bswap

The existing functions defined in intfloat_readwrite.[ch] are
both slow and incorrect (infinities are not handled).
This introduces a new header with fast, inline conversion
functions using direct union punning assuming an IEEE-754
system, an assumption already made throughout the code.
The one use of Intel/Motorola extended 80-bit format is
replaced by simpler code sufficient under the present
constraints (positive normal values).
The old functions are marked deprecated and retained for
compatibility.

Solaris Studio (suncc) has difficulty with filling in
members of a union. Instead, let's retrieve and store the
cpuid() results separately. This is still a compiler bug,
however this fix does not cause a regression on other platforms.
