IMPALA-5572: Timestamp codegen for text scanner

Currently codegen is disabled when scanning text tables with timestamp
columns. The message is "Timestamp not yet supported for codegen."
This patch adds support for timestamp codegen.
A simple query in the comment section of this issue performs a little
better (4%) than interpreted version.
