Description:
Currently PGO (profile guided optimization) is only supported for GCC.
We should add support for Clang as well, since Clang is a supported compiler.

Fixed in 8.0.19.

New FPROFILE_GENERATE and FPROFILE_USE CMake options are available
for experimenting with profile guided optimization (PGO) with GCC.
See the cmake/fprofile.cmake in a MySQL source distribution for
information about using them. These options have been tested with GCC
8 and 9, and with Clang.
