[PULL 22/60] target/xtensa: Use env_archcpu() in update_c[compare|count]()

Posted by Philippe Mathieu-Daudé 1 year ago

When CPUArchState* is available (here CPUXtensaState*), we
can use the fast env_archcpu() macro to get ArchCPU* (here
XtensaCPU*). The QOM cast XTENSA_CPU() macro will be slower
when building with --enable-qom-cast-debug.
