Notes: v3 -> v4: - iatgas.h - LLVM(Clang), ARM, ARM64 support - Use __ASM_NAME macro - Don't fail test on MSVC - Don't end asm macros with "\n\t"
v4 -> v5: - iatgas.h - mark idata sections as RO - loader.c - test for forward export itself
v5 -> v6: - loader.c - Fix compilation warning in format string
v6 -> v7: - forward4.c - fix building without MinGW
v7 -> v8: - forward[1-3].c - Call DisableThreadLibraryCalls in DllMain - forward4.c: removed - iatgas.h: removed - sforward.c: new file - loader.c - test static forwarded import using shlwapi -> userenv forward

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?

__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).

This should be part of the normal handling, not a special case at the top. If the process state is corrupted skipping setup_exception_record() will make things even worse. The same thing is true for other platforms.
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.
