[ObjC++] Use the correct EH personality in GNU mode Previously, it would just always use the ObjC DWARF personality, even with SjLj or SEH exceptions. Patch by Jonathan Schleifer, test case by me. llvm-svn: 299306

[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

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.
