Implement W^X-compatible path. Works on Windows and Android, hopefully iOS (untested).
...
Disabled block linking in this mode, can re-enable with some more work later.
To enable W^X on other platforms than iOS, simply change PlatformIsWXExclusive.

Reset memory alloc pointer when jit alloc fails.
...
On Windows x64, we keep track of our last allocation. Once we run out of
our 2GB range, we need to start over or it'll just fail.
Fixes #8021 .

This isn't needed if ABI_CallFunction* is used.
...
AFAICT the only reason for it is to avoid far calls, so we just can't
use CALL() directly. It's works even when it throws on Mac.

Fix crash on Return to Menu in Symbian.
...
We don't want to free the executable code (actually a Chunk+Heap) using same method we use to free memory pages (delete).
This would be the same situation on jailbroken iOS and WP.
Now the JIT code is always allocated and never freed on Symbian.

New UNUSABLE_MMAP code path for platforms that cannot use the required flags (Xbox 360, Symbian). Falls back to malloc() instead.
N1 define for compilers (GCCE) that don't like to assume (int)-1 will safely cast to (char)-1.

Several fixes to build under stricter C++11
...
Add missing #include to various files.
strings.h isn't provided by MSVC so we don't include it there; it's needed
for other OSes/compilers.
Get rid of pre-ISO-C malloc.h includes; malloc is provided by stdlib.h.
Fixes some linuxisms.
Prepend __builtin_ to __clear_cache, calling it without the prefix is a
GNU extension.
