jerryyin f87ceb63eb [AMDGPU] Adding mutex to guard lld:🧝:link interface use 
check-mlir target run tests simultaneously with multiple threads. This caused multiple threads to invoke the `lld:🧝:link()` interface at the same time. Since the interface does not have a thread-safe implementation, add a metex to prevent multi-threaded access.

I discovered this by looking the the failure stack trace. lld/ELF/symbolTable.cpp, SymbolTable::insert() hit into an assert with related to Epoch Trackers. The root cause is to due to there is no protection around the symMap (update) which is implemented in non-thread safe data structure: denseMap.
