[CodeGenCXX] Convert some tests to opaque pointers (NFC) Conversion done using the script at https://gist.github.com/nikic/98357b71fd67756b0f064c9517b62a34. These are tests where the conversion worked out of the box and no manual fixup was performed.

Reland [Clang] skip default argument instantiation for non-defining friend declarations to meet [dcl.fct.default] p4 (#115487) This fixes a crash when instantiating default arguments for templated friend function declarations which lack a definition. There are implementation limits which prevents us from finding the pattern for such functions, and this causes difficulties setting up the instantiation scope for the function parameters. This patch skips instantiating the default argument in these cases, which causes a minor regression in error recovery, but otherwise avoids the crash. The previous attempt #113777 accidentally skipped all default argument constructions, causing some regressions. This patch resolves that by moving the guard to InstantiateDefaultArgument() where the handling of templates takes place. Fixes https://github.com/llvm/llvm-project/issues/113324

[test] Add {{.*}} to make tests immune to dso_local/dso_preemptable/(none) differences For a definition (of most linkage types), dso_local is set for ELF -fno-pic/-fpie and COFF, but not for Mach-O. This nuance causes unneeded binary format differences. This patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} ` if there is an explicit linkage. * Clang will set dso_local for Mach-O, which is currently implied by TargetMachine.cpp. This will make COFF/Mach-O and executable ELF similar. * Eventually I hope we can make dso_local the textual LLVM IR default (write explicit "dso_preemptable" when applicable) and -fpic ELF will be similar to everything else. This patch helps move toward that goal.

Output destructors and constructors in a more natural order. With this patch we output the in the order C2 C1 D2 D1 D0 Which means that a destructor or constructor that call another is output after the callee. This is a bit easier to read IHMO and a tiny bit more efficient as we don't put a decl in DeferredDeclsToEmit. llvm-svn: 196784

[Clang/Test]: Rename enable_noundef_analysis to disable-noundef-analysis and turn it off by default Turning on `enable_noundef_analysis` flag allows better codegen by removing freeze instructions. I modified clang by renaming `enable_noundef_analysis` flag to `disable-noundef-analysis` and turning it off by default.
