cpu: allow the fetch buffer to be smaller than a cache line
the current implementation of the fetch buffer in the o3 cpu
is only allowed to be the size of a cache line. some
architectures, e.g., ARM, have fetch buffers smaller than a cache
line, see slide 22 at:
http://www.arm.com/files/pdf/at-exploring_the_design_of_the_cortex-a15.pdf
this patch allows the fetch buffer to be set to values smaller
than a cache line.
