Convert a clang::Module to non-const to account for a clang API change

lanza · adrian-prantl · commit e18bd9903ca2 · 2020-04-10T09:08:33.000-07:00
An upstream clang changed ASTSourceDescriptor to not have a const Module pointer. const_cast here to make this agree. (cherry picked from commit a49bcee)
