Commit 701714b10a77aee62cf2ad3e25db9e2dfd418780 in impala's branch refs/heads/master from Tamas Mate

IMPALA-10379: Add missing HiveLexer classes to shared-deps
HIVE-19064 introduced additional lexer classes that are required during
runtime. This commit adds the missing HiveLexer lexer classes to the
shared-deps. Without these classes queries such as 'select 1 as "``"'
would fail with 'NoClassDefFoundError'.
Testing:
- added a misc.test to verify that the classes are available and that
IMPALA-9641 is fixed by HIVE-19064
