  Log:
  Tweak how the MD code calls the fooclock() methods some.  Instead of
  passing a pointer to an opaque clockframe structure and requiring the
  MD code to supply CLKF_FOO() macros to extract needed values out of the
  opaque structure, just pass the needed values directly.  In practice this
  means passing the pair (usermode, pc) to hardclock() and profclock() and
  passing the boolean (usermode) to hardclock_cpu() and hardclock_process().
  Other details:
  - Axe clockframe and CLKF_FOO() macros on all architectures.  Basically,
    all the archs were taking a trapframe and converting it into a clockframe
    one way or another.  Now they can just extract the PC and usermode values
    directly out of the trapframe and pass it to fooclock().
  - Renamed hardclock_process() to hardclock_cpu() as the latter is more
    accurate.
  - On Alpha, we now run profclock() at hz (profhz == hz) rather than at
    the slower stathz.
  - On Alpha, for the TurboLaser machines that don't have an 8254
    timecounter, call hardclock() directly.  This removes an extra
    conditional check from every clock interrupt on Alpha on the BSP.
    There is probably room for even further pruning here by changing Alpha
    to use the simplified timecounter we use on x86 with the lapic timer
    since we don't get interrupts from the 8254 on Alpha anyway.
  - On x86, clkintr() shouldn't ever be called now unless using_lapic_timer
    is false, so add a KASSERT() to that affect and remove a condition
    to slightly optimize the non-lapic case.
  - Change prototypeof  arm_handler_execute() so that it's first arg is a
    trapframe pointer rather than a void pointer for clarity.
  - Use KCOUNT macro in profclock() to lookup the kernel profiling bucket.
  
  Tested on:      alpha, amd64, arm, i386, ia64, sparc64
