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...

target-alpha: Split up FPCR value into separate fields.

The fpcr_exc_status, fpcr_exc_mask, and fpcr_dyn_round fields
are stored in <softfloat.h> format for convenience during
regular execution.

Revert the addition of float_exception_mask to float_status,...

target-alpha: Reduce internal processor registers for user-mode.

The existing set of IPRs is totally irrelevant to user-mode emulation.
Indeed, they most are irrelevant to implementing kernel-mode emulation,
and would only be relevant to PAL-mode emulation, which I suspect that...

target-alpha: Clean up arithmetic traps.

Replace the EXCP_ARITH_OVERFLOW placeholder with the complete
set of bits from the EXC_SUM IPR. Use them in the existing
places where we raise arithmetic exceptions.

Fix incorrect exception_index use

env->exception_index should be cleared with -1, not 0.

target-alpha: Fix float32_to_s vs zero exponent.

There was a bug in float32_to_s that incorrectly mapped a zero exponent
to 0x38. This meant 0.0f != 0. At the same time, fix a generic type
punning bug in helper_memory_to_s and helper_s_to_memory.
