Profile runtime can generate an empty raw profile (when there is no function in the shared library). This empty profile is treated as a text format profile. A test format profile without the flag of "#IR" is thought to be a clang generated profile. So in llvm profile merging, we will get a bogus warning of "Merge IR generated profile with Clang generated profile." The fix here is to skip the empty profile (when the buffer size is 0) for profile merge.
