powerpc: strtok{_r} optimization for powerpc64

This patch optimizes strtok and strtok_r for POWERPC64.
A table of 256 characters is created and marked based on
the 'accept' argument and used to check for any occurance on
the input string.Loop unrolling is also used to gain improvements.
Fix for test "malloc_usable_size: expected 7 but got 11"

[BZ #17581] The checking chain of unused chunks was terminated by a hash of
the block pointer, which was sometimes confused with the chunk length byte.
The chain is now terminated by a NULL byte.
