Merging r215295:

builtins: correct __umodsi3, __udivsi3 on ARM
When building the builtins for a modern CPU (idiv support), __umodsi3 was
completely incorrect as it would behave as __udivmosi3, which takes a tertiary
parameter which is a pointer.
__udivsi3 was also incorrect, returning the remainder in r1. Although this
would not result in any crash or invalid behaviour as r1 is a caller saved
register in AAPCS, this is unnecessary. Simply perform the division ignoring
the remainder.
