Remove unused function parameter from cpu_restore_state

The previous patch removed the need for parameter puc.
Is is now unused, so remove it.

target-alpha: use new float64_unordered_quiet() function

Use float64_unordered_quiet() in helper_cmptun() instead of doing the
the comparison manually.

According to the "Alpha Compiler Writer's Guide", we should use the
_quiet version here, as CMPTUN and CMPTEQ should generate InvalidOp...

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....

The softfloat functions float*_is_nan() were badly misnamed,

target-alpha: Implement RPCC.

A minimal implementation that more or less corresponds to the

target-alpha: Fix float32_to_s vs zero exponent.

There was a bug in float32_to_s that incorrectly mapped a zero exponent
