  1. Character.isWhitespace(-1) returns false 

    Fix scala-native#3154

Previously, `Character.isWhitespace(-1)` and
`Character.isLowerCase(-1)` throw
`java.lang.ArrayIndexOutOfBoundsException: -1`.
However, they should return `false` as other java std libraries do.

We may want to fix `getTypeLT256`, but this commit guaranteed that
the codepoint is gte 0 on call-site of `getTypeLT256` for
not introducing the duplicated check of `codePoint < 0`.
