PowerPC: optimized strpbrk for POWER7
This patch add an optimized strpbrk for POWER7 by using a different algorithm than default implementation: it constructs a table based on the 'accept' argument and use this table to check for any occurance on the input string. The idea is similar as x86_64 uses. For PowerPC some tunings were added, such as unroll loops and memory clear using VSX instructions.
