accel/tcg: Allow the second page of an instruction to be MMIO
If an instruction straddles a page boundary, and the first page
was ram, but the second page was MMIO, we would abort. Handle
this as if both pages are MMIO, by setting the ram_addr_t for
the first page to -1.

linux-user/sparc: Raise SIGILL for all unhandled software traps
The linux kernel's trap tables vector all unassigned trap
numbers to BAD_TRAP, which then raises SIGILL.

linux-user: Always exit from exclusive state in fork_end()
fork()ed processes currently start with
current_cpu->in_exclusive_context set, which is, strictly speaking, not
correct, but does not cause problems (even assertion failures).
With one of the next patches, the code begins to rely on this value, so
fix it by always calling end_exclusive() in fork_end().

Log Message:
-----------
cpus: Make {start,end}_exclusive() recursive
Currently dying to one of the core_dump_signal()s deadlocks, because
dump_core_and_abort() calls start_exclusive() two times: first via
stop_all_tasks(), and then via preexit_cleanup() ->
qemu_plugin_user_exit().
There are a number of ways to solve this: resume after dumping core;
check cpu_in_exclusive_context() in qemu_plugin_user_exit(); or make
{start,end}_exclusive() recursive. Pick the last option, since it's
the most straightforward one.

util/cacheflush: fix cache on windows-arm64
ctr_el0 access is privileged on this platform and fails as an illegal
instruction.
Windows does not offer a way to flush data cache from userspace, and
only FlushInstructionCache is available in Windows API.
The generic implementation of flush_idcache_range uses,
__builtin___clear_cache, which already use the FlushInstructionCache
function. So we rely on that.

sysemu/os-win32: fix setjmp/longjmp on windows-arm64
Windows implementation of setjmp/longjmp is done in
C:/WINDOWS/system32/ucrtbase.dll. Alas, on arm64, it seems to *always*
perform stack unwinding, which crashes from generated code.
By using alternative implementation built in mingw, we avoid doing stack
unwinding and this fixes crash when calling longjmp.
