Subject: [SPARK-7956] [SQL] Use Janino to compile SQL expressions into
 bytecode

In order to reduce the overhead of codegen, this PR switch to use Janino to compile SQL expressions into bytecode.

After this, the time used to compile a SQL expression is decreased from 100ms to 5ms, which is necessary to turn on codegen for general workload, also tests.
