* 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.
* data/localplt-arm-linux-gnueabi.data: New.
* sysdeps/arm/bsd-_setjmp.S: Use HIDDEN_JUMPTARGET to call
__sigsetjmp.
* sysdeps/arm/bsd-setjmp.S: Likewise.
* sysdeps/arm/eabi/aeabi_localeconv.c: Use __localeconv.
* sysdeps/arm/eabi/find_exidx.c (__gnu_Unwind_Find_exidx): Use
__dl_iterate_phdr.
* sysdeps/arm/eabi/setjmp.S: Add hidden_def (__sigsetjmp).
* sysdeps/arm/memmove.S: Use HIDDEN_JUMPTARGET to call memcpy from
within libc.
* sysdeps/arm/setjmp.S: Add hidden_def (__sigsetjmp).
* sysdeps/unix/sysv/linux/arm/clone.S: Use HIDDEN_JUMPTARGET to
call _exit.
* sysdeps/unix/sysv/linux/arm/ioperm.c (init_iosys): Use __sysctl,
__readlink and fgets_unlocked.
(_ioperm): Use __open and __close.
Add "java" and "iwmmxt".
* sysdeps/unix/sysv/linux/arm/dl-procinfo.h: Use <sysdep.h> for
HWCAP values.
(_DL_HWCAP_COUNT): Increase to 10.
* sysdeps/unix/sysv/linux/arm/sysdep.h (HWCAP_ARM_SWP,
HWCAP_ARM_HALF, HWCAP_ARM_THUMB, HWCAP_ARM_26BIT,
HWCAP_ARM_FAST_MULT, HWCAP_ARM_FPA, HWCAP_ARM_VFP, HWCAP_ARM_EDSP,
HWCAP_ARM_JAVA, HWCAP_ARM_IWMMXT): Define.
* sysdeps/arm/eabi/setjmp.S (__sigsetjmp): Save iWMMXt registers
if HWCAP_ARM_IWMMXT set. Don't include <asm/procinfo.h>. Use
HWCAP_ARM_VFP instead of HWCAP_VFP.
* sysdeps/arm/eabi/__longjmp.S (__longjmp): Restore iWMMXt
registers if HWCAP_ARM_IWMMXT set. Don't include
<asm/procinfo.h>. Use HWCAP_ARM_VFP instead of HWCAP_VFP.
