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...

Fix incorrect exception_index use

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

target-alpha: Fix cvtlq.

We were missing the 0xc0000000 mask, leading to incorrect results.

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.

target-alpha: Implement fp branch/cmov inline.

The old fcmov implementation had a typo:
- tcg_gen_mov_i64(cpu_fir[rc], cpu_fir[ra]);
which moved the condition, not the second source, to the destination.

But it's also easy to implement the simplified fp comparison inline....

target-alpha: Fix compiler warning for gcc-4.3 (and older)

"Old" compilers obviously are not able to recognise
that all cases are handled here:

qemu/target-alpha/helper.c:70: error: ‘round_mode’ may be used uninitialized in this function

A small modification helps the compiler to do its jobs....
