This is both an optimisation and a cleanup.
This converts code like
aStr.indexOf("XX") == 0
to
aStr.startsWith("XX")
and converts code like
aStr.lastIndexOf("XXX") == aStr.getLength() - 3
to
aStr.endsWith("XXX")
Note that in general
aStr.lastIndexOf("X") == aStr.getLength() - 1
converts to
aStr.isEmpty() || aStr.endsWith("X")
so I used the surrounding context to determine if aStr could be empty
when modifying the code.
