Summary:
rL277342 made RecursiveASTVisitor visit lambda capture initialization
expressions (these are the Exprs in LambdaExpr::capture_inits()).
jdennett identified two issues with rL277342 (see comments there for details):
- It visits initialization expressions for implicit lambda captures, even if
shouldVisitImplicitCode() returns false.
- It visits initialization expressions for init captures twice (because these
were already traveresed in TraverseLambdaCapture() before rL277342)
This patch fixes these issues and moves the code for traversing initialization
expressions into TraverseLambdaCapture().
This patch also makes two changes required for the tests:
- It adds Lang_CXX14 to the Language enum in TestVisitor.
- It adds a parameter to ExpectedLocationVisitor::ExpectMatch() that specifies
the number of times a match is expected to be seen.

Summary:
Lambda capture initializations are part of the explicit source code and
therefore should be visited by default but, so far, RecursiveASTVisitor does not
visit them.
This appears to be an oversight. Because the lambda body needs custom handling
(calling TraverseLambdaBody()), the DEF_TRAVERSE_STMT for LambdaExpr sets
ShouldVisitChildren to false but then neglects to visit the lambda capture
initializations. This patch adds code to visit the expressions associated with
lambda capture initializations.
