reason about and less error prone. The core idea is to fully parse the text without trying to identify passes or structure. This is done with a single state machine. There were various bugs in the logic around this previously that were repeated and scattered across the code. Having a single routine makes it much easier to fix and get correct. For example, this routine doesn't suffer from PR28577. Then the actual pass construction is handled using *much* easier to read code and simple loops, with particular pass manager construction sunk to live with other pass construction. This is especially nice as the pass managers *are* in fact passes. Finally, the "implicit" pass manager synthesis is done much more simply by forming "pre-parsed" structures rather than having to duplicate tons of logic. One of the bugs fixed by this was evident in the tests where we accepted a pipeline that wasn't really well formed. Another bug is PR28577 for which I have added a test case. The code is less efficient than the previous code but I'm really hoping that's not a priority. ;] Thanks to Sean for the review!
