Compiling Win32 ARM64

[Gerdya]

After Microsoft released the remote debug tools for ARM64 i went back to debug my issue.

I am happy to report that i have found the issue:

In JitArm64_BackPatch.cpp

Code:

m_fault_to_handler.erase(slow_handler_iter);

  emitter.FlushIcache();

  ctx->CTX_PC = (u64)slow_handler_iter->first;

Rootcause:

slow_handler_iter->first is accessed after element has been removed from the std::map.
Issue was that PC got randomly (rarely) a wrong value and crashed after return from exception.

After doing the erase operation after updating the context JitARM64 is working now for Windows!
