Wenlei He 35a6ef8d30 [AutoFDO] Make call targets order deterministic for sample profile ...

Summary:
StringMap is used for storing call target to frequency map for AutoFDO. However the iterating order of StringMap is non-deterministic, which leads to non-determinism in AutoFDO profile output. Now new API getSortedCallTargets and SortCallTargets are added for deterministic ordering and output.

Roundtrip test for text profile and binary profile is added.
