In get_ite() and update_ite() we work with a 12-byte in-guest-memory

Currently the ITS accesses each 8-byte doubleword in a 4-doubleword

awkward because the individual command processing functions have
ended up with code to handle "load more doublewords out of the

The get_ite() code has some awkward nested if statements; clean
them up by returning early if the memory accesses fail.

The sgx_epc_get_section stub is reachable from cpu_x86_cpuid. It
should not assert, instead it should just return true just like
the "real" sgx_epc_get_section does when SGX is disabled.

In get_ite() we currently return the caller some of the fields of an
Interrupt Table Entry via a set of pointer arguments, and validate
some of them internally (interrupt type and valid bit) to return a
simple true/false 'valid' indication. Define a new ITEntry struct
which has all the fields that
The capsicum signal stuff is new with FreeBSD 14, rev 1400026, so only
define QEMU_SI_CAPSICUM there. Only copy _capsicum when QEMU_SI_CAPSICUM
is defined. Default to no info being passed for signals we make no guess
about.

The hcall expects the semantics such that the flush to
In the ITS, a DTE is an entry in the device table, which contains
multiple fields. Currently the function get_dte() which reads one
entry from the device table returns it as a raw 64-bit integer,
which we then pass around in that form, only extracting fields
from it as we need them.

My preference is always to avoid follow-up tweaks if possible :) but
ultimately the decision is up to the QEMU

This adds simple instruction matching to the libinsn.so plugin which
is useful for examining the execution distance between instructions.
For example to track how often we flush in ARM due to TLB updates:
-plugin ./tests/plugin/libinsn.so,match=tlbi
which leads to output like this:
Ping.
The based-on series is already on master, only patch 3 is missing review.
