This PR is part of the LLVM IR LSP server project: https://discourse.llvm.org/t/rfc-ir-visualization-with-vs-code-extension-using-an-lsp-server/87773 To be able to implement goto definition in LSP. One must first have to know what values are referenced on what positions. This PR implements a Location -> Value* map that allows looking up values referenced on queried locations. For example ```llvm %inst = add i32 1, %arg ``` Querying on 0:20 (the location of %arg) would return the Value* of the `%arg`. `getInstuctionLocation(%arg)` would still return the definition of that value Tracking for function arguments was also added in the same fashion a function/instruction/basic block location tracking. The tests were also updated to test the new features a bit.
