(OK, turning off sibling calls has no effect. But it might someday...) As an added benefit, tsc.c is profilable now.

vread_tsc is short and hot, and it's userspace code so the usual
reasons to enable -pg and turn off sibling calls don't apply.

(OK, turning off sibling calls has no effect.  But it might
someday...)

As an added benefit, tsc.c is profilable now.
