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:

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:

A few pretty-printers were returning a quoted string from their
to_string method. It's preferable in gdb to return a lazy string and to
let gdb handle the display by having a "display_hint" method that
returns "string" -- it lets gdb settings (like "set print ...") work, it
handles corrupted strings a bit better, and it passes the information
along to IDEs.
GDB and LLDB pretty printers have some common functionality
and also access some common information, such as the layout of
standard library types. So far, this information has been
duplicated in the two pretty printing python modules. This
commit introduces a common module used by both debuggers.
