Sjoerd Meijer 4dbe73c1ed [ARM] Code size optimisation to lower udiv+urem to udiv+mls instead of a 
library call to __aeabi_uidivmod. This is an improved implementation of
r280808, see also D24133, that got reverted because isel was stuck in a loop.
That was caused by the optimisation incorrectly triggering on i64 ints, which
shouldn't happen because there is no 64bit hwdiv support; that put isel's type
legalization and this optimisation in a loop. A native ARM compiler and testing
now shows that this is fixed.

Patch mostly by Pablo Barrio.
