        src/sys/arch/x86/x86: intr.c

Log Message:
x86: Add dtrace probes for interrupt handler entry and return.

Arguments:

0: interrupt handler function
1: interrupt handler's private cookie argument
2: MD struct intrhand pointer
3: return value (true if relevant to this handler, false if not)

The MD struct intrhand pointer makes the first two arguments
redundant, but we might reuse the signature of the first two
arguments for an MI SDT probe to make it easy to write MI dtrace
scripts for monitoring interrupt handlers.  The MD intrhand can be
used for getting more information about the interrupt like ih_level,
ih_pin, ih_slot, &c., which may not make sense as an MI API.
