[SPARK-14282][SQL] CodeFormatter should handle oneline comment with /* */ properly
## What changes were proposed in this pull request?
This PR improves `CodeFormatter` to fix the following malformed indentations.
```java
/* 019 */ public java.lang.Object apply(java.lang.Object _i) {
/* 020 */ InternalRow i = (InternalRow) _i;
/* 021 */ /* createexternalrow(if (isnull(input[0, double])) null else input[0, double], if (isnull(input[1, int])) null else input[1, int], ... */
/* 022 */ boolean isNull = false;
/* 023 */ final Object[] values = new Object[2];
/* 024 */ /* if (isnull(input[0, double])) null else input[0, double] */
/* 025 */ /* isnull(input[0, double]) */
...
/* 053 */ if (!false && false) {
/* 054 */ /* null */
/* 055 */ final int value9 = -1;
/* 056 */ isNull6 = true;
/* 057 */ value6 = value9;
/* 058 */ } else {
...
/* 077 */ return mutableRow;
/* 078 */ }
/* 079 */ }
/* 080 */
```
After this PR, the code will be formatted like the following.
```java
/* 019 */ public java.lang.Object apply(java.lang.Object _i) {
/* 020 */ InternalRow i = (InternalRow) _i;
/* 021 */ /* createexternalrow(if (isnull(input[0, double])) null else input[0, double], if (isnull(input[1, int])) null else input[1, int], ... */
/* 022 */ boolean isNull = false;
/* 023 */ final Object[] values = new Object[2];
/* 024 */ /* if (isnull(input[0, double])) null else input[0, double] */
/* 025 */ /* isnull(input[0, double]) */
...
/* 053 */ if (!false && false) {
/* 054 */ /* null */
/* 055 */ final int value9 = -1;
/* 056 */ isNull6 = true;
/* 057 */ value6 = value9;
/* 058 */ } else {
...
/* 077 */ return mutableRow;
/* 078 */ }
/* 079 */ }
/* 080 */
```
Also, this issue fixes the following too. (Similar with [SPARK-14185](https://issues.apache.org/jira/browse/SPARK-14185))
```java
16/03/30 12:39:24 DEBUG WholeStageCodegen: /* 001 */ public Object generate(Object[] references) {
/* 002 */ return new GeneratedIterator(references);
/* 003 */ }
```
```java
16/03/30 12:46:32 DEBUG WholeStageCodegen:
/* 001 */ public Object generate(Object[] references) {
/* 002 */ return new GeneratedIterator(references);
/* 003 */ }
```
## How was this patch tested?
Pass the Jenkins tests (including new CodeFormatterSuite testcases.)
