x86: Improve information from domain_crash_synchronous
As it currently stands, the string "domain_crash_sync called from entry.S" is
not helpful at identifying why the domain was crashed, and a debug build of
Xen doesn't help the matter
This patch improves the information printed, by pointing to where the crash
decision was made.
Specific improvements include:
* Moving the ascii string "domain_crash_sync called from entry.S\n" away from
some semi-hot code cache lines.
* Moving the printk into C code (especially as this_cpu() is miserable to use
in assembly code)
* Undo the previous confusing situation of having the
domain_crash_synchronous() as a macro in C code, yet a global symbol in
assembly code.
