7a80547819 [code-completion] Fix compiler crash on implicit member expression in string interpolation 
Resetting Lexer to the start of the line result re-tokenizning whole
string literal as a single token, and go past artificial EOF.
This used to end up with assertion failure or infinite-loop in
no-assertion builds.

Quick fix for: rdar://problem/36881302

67710606e6 [Parse] Move tok::amp_prefix closer to parameter list logic 
The amp_prefix token is currently tolerated in any unary expression
context and then diagnosed later by Sema. This patch changes parsing to
only accept tok::amp_prefix in its allowed position: parameter lists.

This also fixes two "compiler crasher" tests.

7a682a46b9 [Parse] Allow self rebinding 
Instead of parisng identifiers and fallthrough to self, treat `kw_self` the same
as identifiers. This enables binding to self.

6bc96fe447 [Parser] Parse #keyPath in parseExprPostfixWithoutSuffix instead of parseExprUnary 
Moved the call to parseExprKeyPathObjC from parseExprUnary to parseExprPostfixWithoutSuffix. This allows to perform operations on #keyPath(...) as it now parses the suffix for it.
Fixes [Swift JIRA]  (SR-5605) Parser fails on optional #keyPath in cas
Eg. `#keyPath(SomeClass.someProperty).description` is now possible
