History
Andrew Stubbs fbc4c20a80 Fix register conflicts and avoid deprecated instructions in ARM EABI setjmp/longjmp. 
* setjmp and longjmp were using the obsolete fstmiax and fldmiax
  instructions.

* Because of a confusion with two different sets of names for the same
  registers (r0...r3 and a1...a4), if VFP was present then the
  subsequent check for iWMMXt support would use a register that had
  been clobbered by saving/restoring the VFP registers.  (The bit
  being checked was clobbered by a reserved bit of FPSCR that it
  always 0 on present hardware, and no present hardware has both VFP
  and iWMMXt, so this did not cause visible problems.)

	* sysdeps/arm/eabi/setjmp.S (__sigsetjmp): Replace deprecated
	instruction fstmiax with vstmia.
	Correct register conflict and comment.
	* sysdeps/arm/eabi/__longjmp.S (__longjmp): Use vldmia not fldmiax.
	Don't clobber r1/a2 register before testing IWMMXT hwcap.
