[SPARK-7886][SQL] Add built-in expressions to FunctionRegistry.
- ExpressionBuilders is provided with helpers to create a function builder
for each Expression.
- Built-in functions removed from SqlParser when possible. Added to
FunctionRegistry.
TO DO:
- Decide between the reflection and macro implementations of the
expression builder helpers.
- Fix Substring (whose constructor is not well suited for the helper).
- Apply changes to Hive.
