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.
