[ARM, VXworks] Fix build

My patch last week to address selection of be8 linking mode broke the
build for vxworks.  It turns out that this port is one of the few
remaining that is still not based on the EABI/AAPCS.

This patch fixes the build, but I've not really tested it beyond
building the core compiler binaries.  Building a workable compiler
entails downloading a load of vxworks stuff that I'm not sure where to
find.

S/390: Remove loc splitter

The backend splitter splitting a 3 operand load on condition into 2 is
wrong.  The S/390 load on condition instruction might trap on the
memory operand even if the condition is false.  So if the first load
on condition overwrites a register used as part of the memory address
of the second the second might trigger a segfault even if it does not
actually perform the load.

Trying to fix this I noticed that the generated code looks anyway
better without the splitter.  So removing the splitter entirely is the
way to go here.

Support for the SPARC M8 cpu.

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.

[arm] Fix warning in parsecpu.awk

In awk, single quotes within a quoted string do not need escaping.
The existing code causes awk to grumble in the build logs.

* config/arm/parsecpu.awk (gen_comm_data): Do not escape single quotes
in quoted strings.

[arm] Fix cross-native builds

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.
