This adds TM (Transactional Memory) SPRs.
This adds generic spr_read_prev_upper32()/spr_write_prev_upper32() to
handle upper half SPRs such as TEXASRU which is upper half of TEXASR.
Since this is not the only register like that and their numbers go
consequently, it makes sense to generalize the helpers.
This adds a gen_msr_facility_check() helper which purpose is to generate
the Facility Unavailable exception if the facility is disabled.
It is a copy of gen_fscr_facility_check() but it checks for enabled
facility in MSR rather than FSCR/HFSCR. It still sets the interrupt cause
in FSCR/HFSCR (whichever is passed to the helper).
This adds spr_read_tm/spr_write_tm/spr_read_tm_upper32/spr_write_tm_upper32
which are used for TM SPRs.
This adds TM-relates MSR bits definitions. This enables TM in POWER8 CPU class'
msr_mask.

This adds an FSCR (Facility Status and Control Register) SPR. This defines
names for FSCR bits.
This defines new exception type - POWERPC_EXCP_FU - "facility unavailable" (FU).
This registers an interrupt vector for it at 0xF60 as PowerISA defines.
This adds a TCG helper_fscr_facility_check() helper to raise an exception
if the facility is not enabled. It updates the interrupt cause field
in FSCR. This adds a TCG translation block generation code. The helper
may be used for HFSCR too as it has the same format.
The helper raising FU exceptions is not used by this patch but will be
in the next ones.
This adds gen_update_current_nip() to update NIP in DisasContext.
This helper is not used now and will be called before checking for
a condition for throwing an FU exception.

A "mtspr SPRMMUCSR0, reg" always flushed TLB0,
because it passed the SPR number 0x3f4 to the flush routine.
But we want to flush either TLB0 or TBL1 depending on the GPR value.

Define a floating pointer register pointer type in the PowerPC
helper header. The type will be used to pass FPR register operands
to Decimal Floating Point (DFP) helpers. A pointer is used because
the quad word forms of PowerPC DFP instructions operate on adjacent
pairs of floating point registers and thus can be thought of as
arrays of length 2.

Rather than include helper.h with N values of GEN_HELPER, include a
