softfloat: Fix compilation failures with USE_SOFTFLOAT_STRUCT_TYPES

Browse Source 
Make softfloat compile with USE_SOFTFLOAT_STRUCT_TYPES defined, by
adding and using new macros const_float16(), const_float32() and
const_float64() so you can use array initializers in an array of
float16/float32/float64 whether the types are bare or wrapped in the
structs.

[aurelien@aurel32.net: do the same for float16]
