PowerPC: optimized strcspn for PPC64/POWER7
This patch add a optimized strcspn 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 align stack memory to table to 16 bytes (so VSX clean can ran without alignment issues).
