  -----------
  softfloat: Use post test for floatN_mul

The existing f{32,64}_addsub_post test, which checks for zero
inputs, is identical to f{32,64}_mul_fast_test.  Which means
we can eliminate the fast_test/fast_op hooks in favor of
reusing the same post hook.

This means we have one fewer test along the fast path for multiply.

  softfloat: Change tininess_before_rounding to bool

Slightly tidies the usage within softfloat.c and the
representation in float_status.

  softfloat: Name rounding mode enum

Give the previously unnamed enum a typedef name.  Use the packed
attribute so that we do not affect the layout of the float_status
struct.  Use it in the prototypes of relevant functions.

Adjust switch statements as necessary to avoid compiler warnings.
