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.

Advanced SIMD patterns are not predicable, thus they should not have
%? in their output templates. Found when auditing the code for
something else. This has been in my tree for sometime , bootstrapped
and regression tested on armhf for armv7ve+simd as the architectural
base.
