Authentication-results: sourceware.org; auth=none

Hi,

this patch tries to extend tree-ssa-dce.c to remove unnecessary new/delete-pairs (it already does that for malloc/free). Clang does it too and it seems to be allowed by http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2013/n3664.html. I’ve bootstrapped/regtested on aarch64-linux and x86_64-linux.

Best,
Dominik
