[PATCH] D33471: [asan] Remove allow_user_segv_handler on Windows.

This is unfortunate. I want WinASan to behave as much like Linux ASan as possible. The problem is that the MSVC CRT always registers an unhandled exception filter, so we have to overwrite the "user" segv handler if we want ASan to work properly (i.e. catch null derefs) by default.

Anyway, go for it. All the users that we care about (Chrome) manually install ASan's unhandled exception filter for us, so we don't have to fight over which registration wins: https://cs.chromium.org/chromium/src/third_party/crashpad/crashpad/client/crashpad_client_win.cc?type=cs&q=crashpad+asan+package:%5Echromium$&l=119
