[SPARK-15327] [SQL] fix split expression in whole stage codegen
## What changes were proposed in this pull request?
Right now, we will split the code for expressions into multiple functions
when it exceed 64k, which requires that the the expressions are using Row
object, but this is not true for whole-state codegen, it will fail to compile
after splitted.
This PR will not split the code in whole-stage codegen.
## How was this patch tested?
Added regression tests.
