* Implement the majority of parsing support for SE-0039.
* Parse old object literals names using new syntax and provide FixIt.
For example, parse "#Image(imageLiteral:...)" and provide a FixIt to
change it to "#imageLiteral(resourceName:...)". Now we see something like:
test.swift:4:9: error: '#Image' has been renamed to '#imageLiteral
var y = #Image(imageLiteral: "image.jpg")
^~~~~~ ~~~~~~~~~~~~
#imageLiteral resourceName
Handling the old syntax, and providing a FixIt for that, will be handled in a separate
commit.
Needs tests. Will be provided in later commit once full parsing support is done.
* Add back pieces of syntax map for object literals.
* Add parsing support for old object literal syntax.
... and provide fixits to new syntax.
Full tests to come in later commit.
* Improve parsing of invalid object literals with old syntax.
* Do not include bracket in code completion results.
* Remove defunct code in SyntaxModel.
* Add tests for migration fixits.
* Add literals to code completion overload tests.
@akyrtzi told me this should be fine.
* Clean up response tests not to include full paths.
* Further adjust offsets.
* Mark initializer for _ColorLiteralConvertible in UIKit as @nonobjc.
* Put attribute in the correct place.
