This patch tries to make the boundary of clang module and C++20 named module more clear. The changes included: - Rename `TranslationUnitKind::TU_Module` to `TranslationUnitKind::TU_ClangModule`. - Rename `Sema::ActOnModuleInclude` to `Sema::ActOnAnnotModuleInclude`. - Rename `ActOnModuleBegin` to `Sema::ActOnAnnotModuleBegin`. - Rename `Sema::ActOnModuleEnd` to `Sema::ActOnAnnotModuleEnd`. - Removes a warning if we're trying to compile a non-module unit as C++20 module unit. This is not actually useful and makes (the future) implementation unnecessarily complex. This patch meant to be a NFC fix. But it shows that it fixed a bug suprisingly that previously we would surppress the unused-value warning in named modules. Because it shares the same logic with clang modules, which has headers semantics. This shows the change is meaningful.
