target-alpha: Implement IEEE FP qualifiers.
IEEE FP instructions are split up so that the rounding mode
coming from the instruction and exceptions (both masking and
delivery) are handled external to the base FP operation.
FP exceptions are properly raised for non-finite inputs to
instructions that do not indicate software completion.
A shortcut is applied if CONFIG_SOFTFLOAT_INLINE is defined
at the top of translate.c: data is loaded and stored into
FP_STATUS directly instead of using the functional interface
defined by "softfloat.h".
