Fix building compilerplugins with Clang trunk towards Clang 9

...after <https://github.com/llvm/llvm-project/commit/
f19a8b05171a67a290e7d3bd6eba0c95c7b3259c> "Replace ad-hoc tracking of pattern
for an instantiated class-scope" removed
ASTContext::getClassScopeSpecializationPattern.  None of the affected plugins
are enabled by default (nor checked by
solenv/CompilerTest_compilerplugins_clang.mk), so just make sure they still
compile, leaving any potentially necessary adaptions to another commit.
