SSA pass (#1049)
* Add SSA pass which ensures a single assign for each local, except for merged locals where we ensure exactly a single assign from one of the paths leading to that use
* Also add InstrumentLocals pass, useful for debugging locals (similar to InstrumentMemory but for locals)
* Fix a PickLoadSigns bug with tees not being ignored, which was not noticed until now because we ran it on flatter output by default, but the ssa pass uncovered the bug
