This patch serie adds support for the SPARC M8 processor to GCC.
The SPARC M8 processor implements the Oracle SPARC Architecture 2017.

- bmask* instructions are put in their own instruction type.  It makes
  little sense to have them in the same category than array
  instructions.

- Similarly, VIS compare instructions are put in their own instruction
  type.  This is to better accommodate subtypes, which are not quite
  the same than the subtypes of `visl' instructions.

- The introduction of a new `subtype' insn attribute in sparc.md
  avoids the need for adjusting the instruction scheduler DFAs for
  previous cpu models every time a new cpu is introduced.

- The full set of SPARC instructions used in sparc.md, and their
  position in the type/subtype hierarchy, is documented in a comment.
  This eases the modification of the DFA schedulers, and the addition
  of new cpus.

- The M7 DFA scheduler is reworked:

  + To use the new type/subtype hierarchy.
  + The v3pipe insn attribute is no longer needed.
  + More accurate latencies for instructions.
  + The C4 core pipeline is documented in a comment in niagara7.md.

- Support for -mcpu=m8 (we are thus suggesting to abandon the niagaraN
  denomination for M8 and later processors.)

- Support for a new VIS level, VIS4B, covering the new VIS
  instructions introduced in OSA2017 and implemented in the M8.  Also
  built-ins.

- A M8 DFA scheduler:

  + Also based on the new type/subtype hierarchy.
  + The functional units in the C5 core are explicitly documented in a
    comment in m8.md.

The patch I committed yesterday to remove some generated headers from
the source tree unfortunately has a dependency missing that is only
revealed when doing a cross-native or full Canadian cross build.  The
gen* programs were missing a dependency on one of the generated
headers.

Fixed by adding an explicit dependency rule for GTM_H in the same way
as we do for TM_H.

	* config/arm/t-arm (GTM_H): Add arm-cpu.h.

Checked that this restores cross-native building.

This patch implements TARGET_FIXED_CONDITION_CODE_REGS on ARM.

We have two main cases to consider: in Thumb1 code there are no
condition code registers, so we simply return false.  For other
cases we set the the first pointer to CC_REGNUM and the second to
VFPCC_REGNUM iff generating hard-float code.

Running the CSiBE benchmark I see a couple of cases (both in the same
file) where this feature kicks in, so it's not a major change.

	* config/arm/arm.c (arm_fixed_condition_code_regs): New function.
	(TARGET_FIXED_CONDITION_CODE_REGS): Redefine.
