The stack analysis is the foundation to obtain accurate information about the body of a function, which registers are callee-saved, arguments, return values and so on. It is implemented as a pass to run in revamb-dump. This commit also introduces analysis tests specific to what we aim to obtain from the analysis and also some basic unit tests for data structures related to the stack analysis.
