The DTRACE() macro tests both Trace::enabled and the specific flag. This
change uses the same administrative interface for enabling/disabling
tracing, but masks the SimpleFlags settings directly. This eliminates a
load for every DTRACE() test, e.g. DPRINTF.This functionality was not and remains not threadsafe.
On ARM quick regressions, runtime reductions of up to 18% were observed.
