Request for Review : 6553074 : String{Buffer, Builder}.indexOf(Str, int) contains unnecessary allocation

[Mike Duigou]

Hello all;

This patch causes the indexOf and lastIndexOf implementation in 
AbstractStringBuilder to directly compare the character arrays rather than 
making a copy of the substring before comparing.
