The existing grammar was causing discriminant constraints in allocators to be incorrectly parsed as function calls. This change modifies the grammar to more accurately follow the grammar of the language and corrects the issue. Updated the test corpus to add additional allocator tests with numerous subtype indications and qualified expressions for more extensive testing.
