I thought I could make the numbers more stable by using serializing
instructions (cpuid with %eax=0) around the rdtsc, but that just caused some
odd bi-modal behavior where testb/testl and testw/testq "p

Very interesting. I can confirm that testb seems slower on Skylake too.

We should avoid testb optimization. This are latencies:
testb : 33711871
testw : 21204854
testl : 18938530
testq : 18942712
on Haswell. Most of other processors show that testb is the slowest.
