Detailed Description

Helper to describe and deal with positions in the LLVM-IR.

A position in the IR is described by an anchor value and an "offset" that could be the argument number, for call sites and arguments, or an indicator of the "position kind". The kinds, specified in the Kind enum below, include the locations in the attribute list, i.a., function scope and return value, as well as a distinction between call sites and functions. Finally, there are floating values that do not have a corresponding attribute list position.
