target-alpha: Fix system store_conditional

This code contained typos, as it had never been compiled.

Don't bother including executive and supervisor modes.

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: Enable the alpha-softmmu target.

With all of the pre-existing code that would not compile gone,
this is the earliest point at which the target can be enabled.

There is no machine defined yet, so this will crash on startup.
Enable the target anyway, to make sure that further compilation...

target-alpha: Tidy exception constants.

There's no need to attempt to match EXCP_* values with PALcode entry
point offsets. Instead, compress all the values to make for more
efficient switch statements within QEMU.

We will be doing TLB fill within QEMU proper, not within the PALcode,...

target-alpha: Tidy up arithmetic exceptions.

Introduce and use arith_excp, filling in the trap_arg01 IPRs.

target-alpha: Use do_restore_state for arithmetic exceptions.

This gets the PC right after an arithmetic exception. Also tidies
the code in the TLB fault handlers to use common code.

target-alpha: Remove partial support for palcode emulation.

This code does not work, and will be replaced by a bios image.

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...
