We can call do_tb_phys_invalidate from an iocontext, which has
no per-thread tcg_ctx. Move this to tb_ctx, which is global.
The actual update still takes place with a lock held, so only
an atomic set is required, not an atomic increment.

The function is called only at tcg_gen_code() when duplicated TBs
are translated by different threads, and when the tcg_region_tree
is reset. Bake it into the underlying GTree as its value destroy
function to unite these situations.
Also remove tcg_region_tree_traverse() which now becomes useless.

The root trace-events only declares a single TCG event:
$ git grep -w tcg trace-events
trace-events:115:# tcg/tcg-op.c
trace-events:137:vcpu tcg guest_mem_before(TCGv vaddr, uint16_t info) "info=%d", "vaddr=0x%016"PRIx64" info=%d"
and only a tcg/tcg-op.c uses it:
$ git grep -l trace_guest_mem_before_tcg
tcg/tcg-op.c
therefore it is pointless to include "trace-tcg.h" in each target
(because it is not used). Remove it.

While the default config works well enough it does end up enabling a
lot of stuff. For more minimal builds we can select a different list
of devices and let Kconfig work out what we want. For example:
../../configure --without-default-features \
--target-list=arm-softmmu,aarch64-softmmu \
--with-devices-aarch64=minimal
will override the aarch64-softmmu default set of devices with a more
minimal set of devices that just enables the virt and sbsa-ref models.

We currently select CONFIG_V7M for a bunch of our m-profile devices.
The last sticking point is translate.c which cannot be compiled
without expecting v7m support. Express this dependency in Kconfig
rather than in default devices as a stepping stone to a fully
configurable translate.c.
While we are at it we also need to select ARM_COMPATIBLE_SEMIHOSTING
as that is implied for M profile machines.

Add a target-specific Kconfig. We need the definitions in Kconfig so
the minikconf tool can verify they exits. However CONFIG_FOO is only
enabled for target foo via the meson.build rules.
Two architecture have a particularity, ARM and MIPS. As their
translators have been split you can potentially build a plain 32 bit
build along with a 64-bit version including the 32-bit subset.

Some tests for glibc functions cause compilation to emit warnings but
still succeed even if the function is not there. Therefore, change
from cc.compiles to cc.links.

Coverity reports that qemu_parse_config_group is returning without
unrefing the "crumpled" dictionary in case its top level item is a
list. But actually the contract with qemu_record_config_group is
the same as for qemu_parse_config_group itself: if those function
need to stash the dictionary they get, they have to take a reference
themselves (currently this is never the case for either function).
Therefore, just add an unconditional qobject_unref(crumpled) to
qemu_parse_config_group.

Use raise_exception_ra (without error code) when raising the illegal
opcode operation; raise #GP when setting bits 63:32 of DR6 or DR7.
Move helper_get_dr to sysemu/ since it is a privileged instruction
that is not needed on user-mode emulators.

While config-host.mak entries are expanded to "1" for compatibility with
create-config.sh, tests done directly in meson.build expand to the empty
string and cannot be placed to the right of the && operator. Adjust
osdep.h after commit e46bd55d9c ("configure: convert HAVE_BROKEN_SIZE_MAX
to meson", 2021-07-06) changed the way HAVE_BROKEN_SIZE_MAX is defined.
