Previously, each {Indirect,}Query would return a set of Pointers, one per context; now it returns (at most) one Pointer combining information from all contexts.
The old API was more faithful to the implementation concepts, but the analysis is not sufficiently context-sensitive that it makes sense: all existing clients simply throw away the context information---so now we do that for them.
(I may remove the context-sensitivity from the callgraph too, but I'll benchmark that first to see if it reduces precision.)

README
This subrepository holds the source for various packages and tools that support the Go programming language. Some of the tools, godoc and vet for example, are included in binary Go distributions. Others, including the Go oracle and the test coverage tool, can be fetched with "go get". Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs. To submit changes to this repository, see http://golang.org/doc/contribute.html.
