[flang-commits] [flang] [flang][OpenMP] Expand top-level WRAPPER_CLASSs into struct, NFC (PR #162723)

[Krzysztof Parzyszek via flang-commits]

https://github.com/kparzysz created https://github.com/llvm/llvm-project/pull/162723

Most of the time OpenMP types use WRAPPER_CLASS_BOILERPLATE inside of a struct definition. Expand the few remaining cases of WRAPPER_CLASS to use the same form everywhere.

 NFC

Most of the time OpenMP types use WRAPPER_CLASS_BOILERPLATE inside of
a struct definition. Expand the few remaining cases of WRAPPER_CLASS
to use the same form everywhere.
