Add basic CDB support to debuginfo compiletest s, to help catch `*.natvis` regressions, like those fixed in #60687. Several Microsoft debuggers (VS, VS Code, WinDbg, CDB, ...) consume the `*.natvis` files we embed into rust `*.pdb` files. While this only tests CDB, that test coverage should help for all of them. CHANGES src\bootstrap - test.rs: Run CDB debuginfo tests on MSVC targets src\test\debuginfo - issue-13213.rs: CDB has trouble with this, skip for now (newly discovered regression?) - pretty-std.rs: Was ignored, re-enable for CDB only to start with, add CDB tests. - should-fail.rs: Add CDB tests. src\tools\compiletest: - Added "-cdb" option - Added Mode::DebugInfoCdb ("debuginfo-cdb") - Added run_debuginfo_cdb_test[_no_opt] - Renamed Mode::DebugInfoBoth -> DebugInfoGdbLldb ("debuginfo-gdb+lldb") since it's no longer clear what "Both" means. - Find CDB at the default Win10 SDK install path "C:\Program Files (x86)\Windows Kits\10\Debugger\*\cdb.exe" - Ignore CDB tests if CDB not found. ISSUES - `compute_stamp_hash`: not sure if there's any point in hashing `%ProgramFiles(x86)%` - `OsString` lacks any `*.natvis` entries (would be nice to add in a followup changelist) - DSTs (array/string slices) which work in VS & VS Code fail in CDB. - I've avoided `Mode::DebugInfoAll` as 3 debuggers leads to pow(2,3)=8 possible combinations. REFERENCE CDB is not part of the base Visual Studio install, but can be added via the Windows 10 SDK: https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk Installing just "Debugging Tools for Windows" is sufficient. CDB appears to already be installed on appveyor CI, where this changelist can find it, based on it's use here: https://github.com/rust-lang/rust/blob/0ffc57311030a1930edfa721fe57d0000a063af4/appveyor.yml#L227 CDB commands and command line reference: https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/debugger-reference
