[include-mapping] Add C-compatibility symbol entries.

[hokein]

Summary

Extending the python generator:

• to generate C-compatibility symbols
• to generate macros

[kadircet]

clang/tools/include-mapping/gen_std.py

270–271

279

what about having this logic as:

augmented_symbols = [symbol]
augmented_symbols.extend(GetCCompatibilitySymbols(symbol))
for s in augmented_symbols:
  ...

that way we can also encapsulate the rest of c-compat related logic into a more isolated place.

nit: early exits

if header not in c_compat_headers:
  return []
if any(re.fullmatch(x, symbol.name) for x in exception_symbols)::
  return []
...

123

maybe add a comment like: Introduce two more entries, both in the global namespace, one using the C++-compat header and another using the C header.

126

i think it might be better to delete this line.

rebase

[hokein]

update the standard-library tests, and fix a bug.

[hokein]

fix the clangd unittest

This is a behavior change, I think it is probably fine. Would be nice to have a second look.

clang/unittests/Tooling/StandardLibraryTest.cpp

130

this patch exposed a regression caused by 1285172c21ef4867d9f895c0b2ab0f338c46e36f. The test was passed accidentally (both return a nullopt). This patch contains the fix (in StandardLibrary.cpp).

let's change it to stdatomic.h instead.

clang/lib/Tooling/Inclusions/Stdlib/StandardLibrary.cpp

220

nit: i think it's better to early-exit when D is nullptr rather than thinking about that in the rest of the logic.

clang/unittests/Tooling/StandardLibraryTest.cpp

67–68

as mentioned above, you can use stdatomic.h instead

67–68

maybe put everything below into a separate test for CCompat?

71–72

having a more comprehensive test here might be useful, e.g. check that std::int16_t only exists in C++ and just has <cstdint> as a provider. int16_t exists both in C and C++ with relevant providers

stdatomic.h is still a c-compa header (though we don't have a entry in the StdSymbolMap.inc now). <iso646.h> might be better, it is empty file in C++ per C++ standard, so we never have a symbol for this header in C++ symbol map.

oh i actually missed the behaviour change here in the previous version of the code and it seems very subtle.
can we change this function to take in a DeclContext* instead and terminate traversal inside the callsite at TUDecl and only treat TUDecl as global scope here?

Modified this code per the suggestion, hope it is clearer now.

thanks, lgtm again
