__fastfail() is used by the Visual C++ runtime and Windows system libraries to signal that the in-process state is corrupted and unrecoverable.
If __fastfail() is invoked, the NT kernel raises a second-chance non-continuable exception STATUS_STACK_BUFFER_OVERRUN. This quickly terminates the process, bypassing all in-process exception handlers (since they all rely on the potentially corrupted process state).
-- v2: ntdll: Properly parse UDF instruction in ARM. ntdll: Implement __fastfail(). ntdll/tests: Add tests for __fastfail(). include: Define fast fail codes and the __fastfail() intrinsic.

Hi,
While running your changed tests, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?

Today, the UDF instruction handler code assumes Thumb mode code, and cannot recognise the UDF.W form or equivalent instructions in ARM mode encoding.
Fix this by generalising the UDF instruction parser code.
