This brings us a step closer to QOM'ified SH7750 SoC and
fixes b350ab75 (target-sh4: Move PVR/PRR/CVR into SuperHCPUClass)
assuming SuperHCPU type for SUPERH_CPU_GET_CLASS().
Fix Coding Style issues while at it (indentation, braces).

These are needed for any of the Win32 alarm timer implementations.
They are not tied to mmtimer exclusively.

The IO thread, when it senses cpu_single_env == 0, expects exit_request
to be checked later on. A compiler scheduling constraint is not strong
enough to ensure this on modern architecture. A memory fence is needed
as well.

The CONFIG_DEBUG_EXEC define compiles out a single qemu_log_mask()
call, which is a pretty trivial cost even for something in the main
cpu_exec() loop. Having this be conditionally defined means that
'-d exec' on a non-debug build will silently do nothing. Drop the
define and the configure machinery that sets it, in favour of just
always allowing this log option to be enabled at runtime. As a
concession to the mainloopiness, we use qemu_loglevel_mask()+qemu_log()
rather than qemu_log_mask() to avoid the function call overhead.
Note that DEBUG_DISAS is always defined, so removing the
'|| defined(CONFIG_DEBUG_EXEC)' from those conditionals makes
no behavioural change for that logging.

We're moving away from the temporaries stored in env. Make sure we can
differentiate between temp stores and possibly bogus stores for extra
