[ARM] 3049/1: More optimized libgcc functions
Patch from Nicolas Pitre
This patch gets rid of the last C implementations of needed libgcc
functions for the kernel, replacing them with optimized assembly
versions.
Those functions are:
__ashldi3
__ashrdi3
__lshrdi3
__muldi3
__ucmpdi2
The first 3 were lifted from gcc, the other two were written from scratch.
