[SPARK-17108][SQL]: Fix BIGINT and INT comparison failure in spark sql
## What changes were proposed in this pull request?
Add a function to check if two integers are compatible when invoking
`acceptsType()` in `DataType`.
## How was this patch tested?
Manually.
E.g.
```
spark.sql("create table t3(a map<bigint, array<string>>)")
spark.sql("select * from t3 where a[1] is not null")
```
Before:
```
cannot resolve 't.`a`[1]' due to data type mismatch: argument 2 requires
bigint type, however, '1' is of int type.; line 1 pos 22
org.apache.spark.sql.AnalysisException: cannot resolve 't.`a`[1]' due to
data type mismatch: argument 2 requires bigint type, however, '1' is of int
type.; line 1 pos 22
