Issue Description:

The following invalid code crash compiler and source editor (Swift DEV Snapshots 2016-03-16):

func bug( a: inout inout Int ) {}

Result:

Assertion failed: (!objectTy->is<LValueType>() && !objectTy->is<InOutType>() && "cannot have 'inout' or @lvalue wrapped inside an 'inout'"), function get, file /Users/buildnode/jenkins/workspace/oss-swift-package-osx/swift/lib/AST/ASTContext.cpp, line 3297.
