Add ability to test for expected errors in intentions

If an intention test contains `// SHOULD_FAIL_WITH: my_string`, the test
is expected to throw `IntentionTestException("my_string")`. This is
useful for testing whether or not a function that should be called, is
called (a pop-up dialog is displayed, etc.).
Add ability to test for expected intention text

If a testData file contains `// INTENTION_TEXT: ...`, the tested
intention's description must match `...`.
Avoid throwing unchecked exceptions

Make `ResolvedCall.getValueArgumentsByIndex` return null instead of
throwing an InvalidStateException when resolving invalid arguments.
Invalid arguments are a user error (the user specified the invalid
arguments in their code), not a program error.
Add KotlinSignature annotation to RESOLVED_CALL

A ResolvedCall's CallableDescriptor cannot be null.
Add replacement intentions for operator functions

Add intentions for replacing attribute calls that correspond to
overloadable operators with their respective operators.

This commit includes call replacements for:
 * Binary Infix Operators: plus, minus, times, rangeTo, mod, div
 * Unary Prefix Operators: plus, minus, not
 * Array Index Operator: get
 * In Operator: contains
