Previously extractors tried to be stateless with any additional context information needed in order to parse items being passed in via the extraction method. This led to quite cumbersome implementation challenges and awkwardness of use. This patch brings back support for stateful extractors, making the implementation and usage simpler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@305093 91177308-0d34-0410-b5e6-96231b3b80d8
