[llvm-commits] [ASan] remove <new> header (issue 5966077)

[samsonov at google.com]

Reviewers: kcc1, timurrrr_at_google_com,

Message:
#include <new> brings a number of system libraries (e.g. <string.h> on
Windows), which is probably unwanted. We (hopefully) can replace
std::nothrow_t and std::bad_alloc by custom stubs, so that our overload
of new would still work in a user program.
