When building with Clang 14 (using gcc 12 libstdc++ headers), I get:

It complains about the use of std::result_of, which is deprecated in
C++17 and removed in C++20:
https://en.cppreference.com/w/cpp/types/result_of
Given we'll have to transition to std::invoke_result eventually, make a
GDB wrapper to mimimc std::invoke_result, which uses std::invoke_result
for C++ >= 17 and std::result_of otherwise. This way, it will be easy
to remove the wrapper in the future, just replace gdb:: with std::.
Tested by building with gcc 12 in -std=c++11 and -std=c++17 mode, and
clang in -std=c++17 mode (I did not test fully with clang in -std=c++11
mode because there are other unrelated issues).
