Make new.cc definitions weak (#1233)

Browse source 
The STL says that these should be replaceable by user code.

new.cc now defines only a few direct functions (including a free wrapper
that perplexingly is needed since g++ didn’t want to alias "free".) Now,
all of the operators are weak references to those functions.
