Adds cpp bindings for jemalloc, along with necessary autoconf settings. This is mostly to add sized deallocation support, which can't be added from C directly. Sized deallocation is ~10% microbench improvement. * Import ax_cxx_compile_stdcxx.m4 from the autoconf repo, seems like the easiest way to get c++14 detection. * Adds various other changes, like CXXFLAGS, to configure.ac. * Adds new rules to Makefile.in for src/jemalloc-cpp.cpp, and a basic unittest. * Both new and delete are overridden, to ensure jemalloc is used for both. * TODO future enhancement of avoiding extra PLT thunks for new and delete - sdallocx and malloc are publicly exported jemalloc symbols, using an alias would link them directly. Unfortunately, was having trouble getting it to play nice with jemalloc's namespace support. Testing: Tested gcc 4.8, gcc 5, gcc 5.2, clang 4.0. Only gcc >= 5 has sized deallocation support, verified that the rest build correctly. Tested mac osx and Centos. Tested --with-jemalloc-prefix and --without-export. This resolves #202.
