IMPALA-3153: Incorrect behaviour around slash escaping single quotes

This patch adds a sub process, inserting into a slash before a single
quote in a String, to solve this issue that a String is cut off from
the single quote.

Now for the string expressions, containing "'" or "\'", are analysised
well.

Patch Set 2:

Hi, Jim.
If it's proper to add a new query test file into
{IMPALA_HOME}/testdata/workloads/tpch/queries/,
like 'tpch-q1.test'?
Thanks. :)

This change is small enough that it should be re-sent on the new gerrit project Impala-ASF. See https://cwiki.apache.org/confluence/display/IMPALA/How+to+switch+to+Apache-hosted+git

Commit Message:

PS2, Line 7: IMPALA
Please see the comment on this bug first - what does the SQL standard say is the correct behavior?


PS2, Line 9: sub process
What is a "sub process"?


http://gerrit.cloudera.org:8080/#/c/3335/2/fe/src/main/java/com/cloudera/impala/analysis/StringLiteral.java
File fe/src/main/java/com/cloudera/impala/analysis/StringLiteral.java:

Line 79:       str.insert(pos + (count++), '\\');
This seems more complex than iterating over the strong one character at a time, and it also might have quadratic complexity if StringBuilder.insert takes linear time.
