Summary: The compiler does not always generate linkage names. If a function has been inlined and its body elided, its linkage name may not be generated. When the binary executes, the profiler will use its unmangled name when attributing samples. This results in unmangled names in the input profile. We are currently failing hard when this happens. However, in this case all that happens is that we fail to attribute samples to the inlined function. While this means fewer optimization opportunities, it should not cause a compilation failure. This patch accepts all valid function names, regardless of whether they were mangled or not.
