Excessive clock queries causing slowdown on freebsd #38877
Description
On freebsd, the jl_hrtime calls that we use to compute time spent in the compiler appear to be taking 70% of total execution time of compile-heavy julia processes. On linux it's not quite as bad, because this syscall has a special fastpath, but either way, this time is clearly excessive. cc @ianshmean who added this timer in #37678. At the very least, it should only be on in @time.
