672dc5cd87 Nil type check implementation (#15287)
* Nil checking
* Enable current older not nil checking again, run new checking only under flag, skip our test
* Enable tests, work on try/except and bugs, fix notnil tests

* Enable strictNotNil tests (currently with lowercase category) and add some expected output
* Work on try/except/finally: still some things unclear and a lot of code can raise out of try
* Fix the notnil build by going back to the old version of a test which I shouldn't have changed

* Fix test : use action compile
* Work on mutation and aliasing: not finished
* Render var parititions graph, try to understand it, fix a nilcheck if bug
* Rebase, progress on working with partitions
* Improve time logic
* Fix some bugs, use graph indices instead of symbol in nil map
* Fix bugs, test simpler ident aliasing for now, support two mutation levels
* Support ContentMutation and ReAssignment: for now just detect possible re assignment for var parameters of calls
* Enable several simple passing tests
* Cleanup a bit, fix condition/branch infix-related bug
* Remove some files, address some comments by Araq
* Use internalError and no quit for now
* Separate tests with expected warnings and with expected ok, fix a bug with if with a single branch related to copyMap
* Fix new data structures, bugs: make tests pass, disable some for now
* Work on fixing errors with non-sym nodes, aliasing: tests fail
* Work on alias support: simple set-based logic, todo more tests and ref sets?
* Use ref sets: TODO can we think of handle seq-s similar to varpartitions' Araq ones
* Handle defers in one place, stop raising in reverse to make an async test compile with strictNotNil, add a commented out test
* Dot expressions: call/reassignment. Other refactorings and distinct, SeqOfDistinct support. Checkout an older varpartitions
* Work on field tracking
* Backup : trying to fix bugs when running some stdlib stuff for running an async test
* Start a section about strict not nil checking in experimental manual
* Fix experimental strict not nil manual section and move it to another file based on Araq feedback
* Fix unstructured flow and double warning problems, fix manual, cleanup
* Fix if/elif/else : take in account structure according to Araq feedback
* Refactor a bit
* Work on bracket expr support, re-enable tests, clarify in manual/tests/implementation static index support for now
* Work on compiling stdlib and compiler with strictNotNil
* Small fixes to the manual for strictNotNil
* Fix idgen for strict check nil rebase
* Enable some simple tests, remove old stuff, comment out code/print
* Copy the original varpartitions source instead of my changes
* Remove some files

fa84121421 effects: exclude swap() from "indirect calls" assumption (#15504)
swap() will never call any procs passed to it, and so it can be safely
excluded from the "assume indirect calls are taken" effects tracking
rule.

7d6cbf290a Error -> Defect for defects (#13908)
* Error -> Defect for defects

The distinction between Error and Defect is subjective,
context-dependent and somewhat arbitrary, so when looking at an
exception, it's hard to guess what it is - this happens often when
looking at a `raises` list _without_ opening the corresponding
definition and digging through layers of inheritance.

With the help of a little consistency in naming, it's at least possible
to start disentangling the two error types and the standard lib can set
a good example here.

ce9a4ed124 Replace tfHasRequiresInit with a more accurate mechanism
The new mechanism can deal with more complex scenarios such as
not nil field appearing in a non-default case object branch or
a field within a generic object that may depend on a when branch.

The commit also plugs another hole: the user is no longer able
to create illegal default values through seq.setLen(N).

a0eca75182 sink parameter inference for types that have destructors (#13544)
* ensure capitalize doesn't take an inferred sink parameter

* sink parameter inference: first version, for now disabled. Changed that sink parameters can be consumed multiple times in order to adhere to our spec.

* sink inference can now be disabled with .nosinks; sometimes for proc type interop this is required

* fixes yet another critical DFA bug

* better implementation that also understands if expressions etc

* document sink parameter inference and allow for global disabling
