Bulk update .src for changes in the language module.
More test changes required by changes in the language module.
Issue #1681: Fix how we create a Sequence of annotation class instances, to aboid using SequenceBuilder.
Issue #1681: Fix the only test which seesm to test the array -> Sequential conversion :-(
Issue #1681: Remove use of SequenceBuilder from transformation of spread member.
Issue #1681: Bulk update tests now that spread member transformation has changed
Issue #1681: Now the transformation of spread members no longer directly contains a backward branch this test should compile without errors.
Issue #1681: Remove some of the workarounds (and supporting state in the ExpressionTransformer) that were necessary for #929.
Ignored test for #1631: Improve compiler speed for "Hello World" projects

Useful for benchmarking
ClassTransformer: make shortcut refinement trees have implicit tree annotations actual/shared
Add new finer benchmark categories #1631: Improve compiler speed for "Hello World" projects
Fix for #1631: Avoid completing packages just to test for their existence

Much cheaper to not complete them and lazy-complete class files on demand
JavacUtil #1631: faster annotation lookup
Model loader #1631: lazy-load actual/refinedDeclaration because they are expensive and rarely used
Model loader: remove dead code
CompilerTest: the ceylon-spec project actually compiles to bin
Test and updated test .src now that shortcut refinements have proper actual/shared annotations
Updated model loader test for error that will now only be shown when using the actual refined declaration
