Enable -msse4.2, -mavx, -mpopcnt on x86_64 builds This allows the compiler to optimize various memory-access operations, like the ones in TraceProcessor's bit_vector.h. Also add a run-time check that crashes the process in a graceful manner to check that the host CPU actually has the features we are assuming.
