Large compilation unit tests due to large code size or timing out

There unit tests in TestLargeFileCompilation fails on master branch. Part of the reason that the failures were not exposed is that TestLargeFileCompilation was excluded from normal "mvn install" build.

1. testPARQUET_WRITER() : code too large in Copier operator
2. testTEXT_WRITER(): code too large in Copier operator
3. testFILTER() : hit error in Scalar Replacement code. Then time out. The SR error might be related to DRILL-3995.

DRILL-4715 is to address the issues of large code in project operator, and would not solve the above 3 failures. Open this JIRA to keep track of those failures.
