[SampleFDO] Extend SampleProfReader to handle demangled names

Authored by wmi on Mar 6 2018, 9:33 AM.



SampleProfReader assumes function names in the profile are all mangled names. However, there are cases that few demangled names are somehow contained in the profile (usually because of debug info problems), which may trigger parsing error in SampleProfReader and cause the whole profile to be unusable. The patch extends SampleProfReader to handle profiles with demangled names, so that those profiles can still be useful.

Just to confirm, this only applies to text format. Binary format should not have this problem, right?
