PreStmt<CXXNewExpr> was never called.
Additionally, under c++-allocator-inlining=true, PostStmt<CXXNewExpr> was
called twice when the allocator was inlined: once after evaluating the
new-expression itself, once after evaluating the allocator call which, for the
lack of better options, uses the new-expression as the call site.
This patch fixes both problems.
