[clang] [MSVC] Enable unwind tables for ARM The backend now can generate working unwind information for this target. Improve the existing windows-exceptions.cpp testcase to check for the state of unwind tables on all MSVC architectures. Differential Revision: https://reviews.llvm.org/D126862

[Driver] Stop passing -fseh-exceptions for x86_64-windows-msvc -fseh-exceptions is only meaningful for MinGW targets, and that driver already has logic to pass either -fdwarf-exceptions or -fseh-exceptions as appropriate. -fseh-exceptions is just a no-op for MSVC triples, and passing it to cc1 causes unnecessary confusion.

[clang] [MinGW] Default to WinEH (SEH) exception handling instead of Dwarf The relevant runtime libraries have been updated to support this now. Differential Revision: https://reviews.llvm.org/D126871

[MinGW] Use SEH by default on AArch64 The implementation of SEH is pretty mature at this point. Differential Revision: https://reviews.llvm.org/D61591 llvm-svn: 360081

[clang][cli] Squash multiple cc1 -fxxx-exceptions flags into single -exception-model=xxx option This patch enables marshalling of the exception model options while enforcing their mutual exclusivity. The clang driver interface remains the same, this only affects the cc1 command line. Depends on D93215. Reviewed By: dexonsmith Differential Revision: https://reviews.llvm.org/D93216

MINGW-DWARF: -exception-model=dwarf
Fix -fno-unwind-tables -fasynchronous-unwind-tables to emit unwind tables This matches GCC. Change the CC1 option to encode the unwind table level (1: needed by exceptions, 2: asynchronous) so that we can support two modes in the future.
