Fix suggested by Yuanfang Chen: Non-distinct debuginfo is attached to the function due to the undecorated declaration. Later, when seeing the function definition and `nodebug` attribute, the non-distinct debuginfo should be cleared. Reviewed By: dblaikie Differential Revision: https://reviews.llvm.org/D104777
