Summary: The name of the synthesized constants for constant initialization was using mangling for statics, which isn't generally correct and (in a yet-uncommitted patch) causes the mangler to assert out because the static ends up trying to mangle function parameters and this makes no sense. Instead, mangle to `"__const." + FunctionName + "." + DeclName`. Reviewers: rjmccall Subscribers: dexonsmith, cfe-commits Differential Revision: https://reviews.llvm.org/D54055 llvm-svn: 346915
