Two new matchers for CXXNewExpr are added which may be useful e.g. in clang-tidy checkers. One of them is isArrayForm which matches new but not plain new. The other one, hasArraySize matches new for a given size.
We typically try to match the AST method names with the matcher names when possible, so this should be named isArray().
Matcher renamed to isArray.
