This is an exclusive TCG helper. Gating it with CONFIG_TCG and changing
meson.build accordingly will prevent problems --disable-tcg and
--disable-linux-user later on.
We're also changing the uses of !kvm_enabled() to tcg_enabled() to avoid
adding "defined(CONFIG_TCG)" ifdefs, since tcg_enabled() will be
defaulted to false with --disable-tcg and the block will always be
skipped.

This patch starts an IBM Power8+ compatible PMU implementation by adding
the representation of PMU events that we are going to sample,
PMUEventType. This enum represents a Perf event that is being sampled by
a specific counter 'sprn'. Events that aren't available (i.e. no event
was set in MMCR1) will be of type 'PMU_EVENT_INVALID'. Events that are
inactive due to frozen counter bits state are of type
'PMU_EVENT_INACTIVE'. Other types added in this patch are
PMU_EVENT_CYCLES and PMU_EVENT_INSTRUCTIONS. More types will be added
later on.
Let's also add the required PMU cycle overflow timers. They will be used
to trigger cycle overflows when cycle events are being sampled. This
timer will call cpu_ppc_pmu_timer_cb(), which in turn calls
fire_PMC_interrupt(). Both functions are stubs that will be implemented
later on when EBB support is added.
Two new helper files are created to host this new logic.
cpu_ppc_pmu_init() will init all overflow timers during CPU init time.

Divided mmu_helper.c in 2 files, functions inside #ifdef CONFIG_SOFTMMU
stayed in mmu_helper.c, other functions moved to mmu_common.c. Updated
meson.build to compile mmu_common.c and only compile mmu_helper.c when
CONFIG_TCG is set.
Moved function declarations, #define and structs used by both files to
internal.h except for functions that use structures defined in cpu.h,
those were moved to cpu.h.

updated build file to not compile some sources that are unnecessary if
TCG is disabled on the system.

Created a file with stubs needed to compile disabling TCG. *_ppc_opcodes
were created to make cpu_init.c have a few less ifdefs, since they are
not needed. softmmu_resize_hpt_* have to be created because the compiler
can't automatically know they aren't used, but they should never be
reached.

finished isolation of CPU initialization logic from
translation logic. CPU initialization now only has common code
and may or may not call accelerator-specific code, as the
build options require.

Move the functions to a new file, helper_regs.c.
Note int_helper.c was relying on helper_regs.h to
indirectly include qemu/log.h.

Similar to hw_arch, each architecture defines two sourceset which are placed in
dictionaries target_arch and target_softmmu_arch. These are then picked up
from there when building the per-emulator static_library.
