Add test case for crash triggered in `swift::ASTVisitor`. Current number of unresolved compiler crashers: 121 (5184 resolved) Assertion failure in [`lib/Sema/CSApply.cpp (line 2599)`](https://github.com/apple/swift/blob/master/lib/Sema/CSApply.cpp#L2599): ``` Assertion `conforms && "Type does not conform to protocol?"' failed. When executing: swift::Expr *<anonymous namespace>::ExprRewriter::visitArrayExpr(swift::ArrayExpr *) ``` Assertion context: ``` bool conforms = tc.conformsToProtocol(arrayTy, arrayProto, cs.DC, ConformanceCheckFlags::InExpression, &conformance); (void)conforms; assert(conforms && "Type does not conform to protocol?"); // Call the witness that builds the array literal. // FIXME: callWitness() may end up re-doing some work we already did // to convert the array literal elements to the element type.

typelayout_based_value_witness.swift failed on iphoneos-arm64e due to an extra line of IR that gets generated. That meant the swift_release line had 'swiftlang#7' instead of 'swiftlang#6'. The test shouldn't be checking for 'swiftlang#6' anyways, so removed that check which causes the test to now pass.

This inserts a suitably named function into the stack trace whenever a dynamic cast failure involves a NULL source or target type. Very often, crash logs include backtraces with function names but no log output; with this change, such a backtrace might look like the following -- note `TARGET_TYPE_NULL` in the function name here to mark the missing type information: ``` frame #0: __pthread_kill + 8 frame swiftlang#1: pthread_kill + 288 frame swiftlang#2: abort + 128 frame swiftlang#3: swift::fatalErrorv() frame swiftlang#4: swift::fatalError() frame swiftlang#5: swift_dynamicCastFailure_TARGET_TYPE_NULL() frame swiftlang#6: swift::swift_dynamicCastFailure() frame swiftlang#7: ::swift_dynamicCast() ``` Resolves rdar://130630157
