Sailesh Mukil 1c46cab5c6 IMPALA-2084: SPLIT_PART and REGEXP_LIKE functions for Tableau pushdown ...

Added the SPLIT_PART and the REGEXP_LIKE builtin functions and tests for both.
The REGEXP_LIKE has an optional third parameter which if used, uses a different
'prepare' function (RegexpLikePrepare in like-predicate.cc) so that the appropriate
options can be set in the RE2 library.

Added a patch for the RE2 library so that the 'dot matches all' option is exposed
via the RE2 class.

Fixed a bug in the case when the function to be evaluated for the WHERE clause
operates on constants, proper cleanup isn't guaranteed on certain edge cases.
