* arm/lib1funcs.asm (ARM_DIV_MOD_BODY) split into ARM_DIV_BODY
and ARM_MOD_BODY.
(ARM_MOD_BODY): rewritten. added clz insns for __ARM_ARCH__ >= 5.
(ARM_DIV_BODY): added clz insns for __ARM_ARCH__ >= 5,
added better divisor alignment in the other case.
(ARM_DIV2_ORDER): added, finds the order of a single bit divisor.
(__divsi3, __udivsi3, __modsi3, __umodsi3): rewritten using the
macros above, add fast exits for divisor >= dividend, etc.
