Adding a few bandwidth tests.

New tests being added:
- copy_bandwidth: Gathers the copy bandwidth using four different
  hand-coded assembler routines and using memcpy.
- write_bandwidth: Gathers the write bandwidth using four different
  hand-coded assembler routines and using memset.
- per_core_bandwidth: Launches a thread of any one of the write/copy
  bandwidth tests locked to every available core on the machine.
- multithread_bandwidth: Launches a user specified number of threads running
  any one of the write/copy bandwidth tests.

Each of the tests can be modified as to the size of the data to manipulate
and the number of loops to run.

Deleted tests:
- memcpy (a better memcpy benchmark can be found in system/extras/micro_bench)
- memset (a better memset benchmark can be found in system/extras/micro_bench)
- memcmp (no real replacement, but I plan to add this to micro_bench)
- strlen (no real replacement, but I plan to add this to micro_bench)
- cpufreq (this doesn't work any more)

All verification tests have been mostly shifted to system/extras/libc_test.

Merge from internal master.
