target-alpha: Merge HW_REI and HW_RET implementations.

target-alpha: Rationalize internal processor registers.

Delete all the code that tried to emulate the real IPRs of some
unnamed CPU. Replace those with just 3 slots that we can use to
communicate trap information between the helper functions that
signal exceptions and the OS trap handler....

target-alpha: Fix translation of PALmode memory insns.

All of the "raw" memory accesses should be "phys" instead. Fix
some confusion about argument ordering of the store routines.
Fix the implementation of store-conditional.

Delete the "alt-mode" helpers. Because we only implement two...

target-alpha: Implement rs/rc properly.

This is a per-cpu flag; there's no need for a spinlock of any kind.

We were also failing to manipulate the flag with $31 as a target reg
and failing to clear the flag on execution of a return-from-interrupt
instruction....

target-alpha: Implement cvtlq inline.

It's a simple shift and mask sequence.

It's a simple mask and shift sequence.
Also, fix a typo in the actual masks used.

target-alpha: Add flags markups to helpers.h.

Almost all alpha helpers are at least TCG_CALL_CONST
and a fair few are also TCG_CALL_PURE.

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: 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: remove amask helper

The direct use of helper_amask in translate.c was bogus (as env is not
assigned). Directly code amask in tcg and remove the helper.
