Can I assume weak refs to be supported, or how do I check for whether
they are? What's your preference?
G++ does support targets without weak symbols, but I imagine we can
decide not to support libitm on such targets.

#include <stdint.h> and compare UINTPTR_MAX to UINT64_MAX?
Presumably that header is already included to use uint32_t and
uint64_t, but even if not there are pre-defined versions of those
macros that don't need any header, __UINTPTR_MAX__ and __UINT64_MAX__.
