Vedant Kumar 19b73c8e94 [Coverage] Add an API to retrive all instantiations of a function (NFC) ... The CoverageMapping::getInstantiations() API retrieved all function records corresponding to functions with more than one instantiation (e.g template functions with multiple specializations). However, there was no simple way to determine *which* function a given record was an instantiation of. This was an oversight, since it's useful to aggregate coverage information over all instantiations of a function. llvm-cov works around this by building a mapping of source locations to instantiation sets, but this duplicates logic that libCoverage already has (see FunctionInstantiationSetCollector). This change adds a new API, CoverageMapping::getInstantiationGroups(), which returns a list of InstantiationGroups. A group contains records for each instantiation of some particular function, and also provides utilities to get the total execution count within the group, the source location of the common definition, etc. This lets removes some hacky logic in llvm-cov by reusing FunctionInstantiationSetCollector and makes the CoverageMapping API friendlier for other clients. llvm-svn: 309904		2017-08-02 23:35:25 +00:00
