Added predictor stride argument(s) to subtract functions

Patch set 2: 64 bit build fix
Patch set 3: 64 bit crash fix

[Tero]
Patch set 4: Updated ARMv6 and NEON assembly.
             Added also minor NEON optimizations to subtract
             functions.

Patch set 5: x86 stride bug fix

ARMv6 optimized subtract functions

Adds following ARMv6 optimized functions to encoder:
  - vp8_subtract_b_armv6
  - vp8_subtract_mby_armv6
  - vp8_subtract_mbuv_armv6

Gives 1-5% speed-up depending on input sequence and encoding
parameters. Functions have one stall cycle inside the loop body
on Cortex pipeline.
