* Implement NonInvariantChildProperty detection
See https://github.com/vimeo/psalm/issues/4184
* Delete test cases with 'parentSetsWiderTypeInConstructor'
As I understand it these are not valid test cases. They
emit NonInvariantPropertyType issues which seems correct - the property
type variation is I think a latent bug in the sample code.
* Reduce shortcode for NonInvariantPropertyType to 1+max used shortcode on master
* Track references on global variables
Add global type references to the type map, and fix up unused detection on global variables.
* Add null assertions
* PHPCS
* Add constant fetch to reference map
To support showing constant types on hover of constant references, we need to add them to the ref map.
* Fix root constants
* PHPCBF
* Add completions for known array keys
* Use dynamic gap value
* Provide completions for known type contexts
* Fix formatting
* Remove trailing comma
* PHPCS fixes
* Remove support for literal floats
* Fix test for floats
* [DOCS] Extend documentation on global variables configuration
* [DOCS] Synchronize meaning of @psalm-taint-source input with source code
* [DOCS] Add documentation for conditional @psalm-taint-escape
* [DOCS] Add documentation for @psalm-taint-unescape
* Remove ReflectionType::getName(), move ReflectionType::isBuiltin()
* `ReflectionType::getName()` was never there: https://3v4l.org/1iZt4
* `ReflectionType::isBuiltin()` was moved to
`ReflectionNamedType::isBuiltin()` in PHP 8
Fixesvimeo/psalm#5089
* Fix test
* Mark test as php 8.0 only
* Use separate exit code to indicate Psalm finding issues
This will allow to distinguish successful run that found some issues
from crashes.
* Fix e2e test expectations
* Documented exit statuses
* Support compleitions on class references
This provides completions on class references (as opposed to initiated objects via the type map), so you can do `MyClass::` and get completitions for static methods and constants etc.
* Only provide completions for references that don't exist
