- Eliminate extra subcs instruction. I have not noticed before that we
...
always perform substraction now, so no instruction could be rordered
to eliminate the conditional substraction.

- Fix strncmp on arm. Return 0 as result without performing the
...
main cycle only if the len passed is equal to 0. If end address
overflows use last possible address as the end address.

Change the test at the beginning of strncmp(), from being if (len - 1) < 0
...
to if (len == 0).
The length is supposed to be unsigned, so len - 1 < 0 won't happen except
if len == 0 anyway, and it would return 0 when it shouldn't, if len was
> INT_MAX.
