This patch also adds a GetReturnType() method to FunctionContext. This
is staging for the expr refactoring.

FromUtc and ToUtc use thirdparty libraries which use inline asm which
isn't currently supported with JIT. The UDFs are included in this
commit, but the function symbols were not changed in
impala_functions.py

Float/Doubles are lossy so using those as the default literal type
is problematic.

This patch allows the text scanner to read 'inf' or 'Infinity' from a
row and correctly translate it into floating-point infinity. It also
adds is_inf() and is_nan() builtins.
Finally, we change the text table writer to write Infinity and NaN for
compatibility with Hive.
In the future, we might consider adding nan / inf literals to our
grammar (postgres has this, see:
http://www.postgresql.org/docs/9.3/static/datatype-numeric.html).

It would have been convenient today to know the largest values that
Impala accepts for its integer types. This patch adds max and min
builtins for our numeric types.

This patch cleans up analysis and execution of scalar and aggregate functions
so that there is no difference between how builtins and user functions are
handled. The only difference is that the catalog is populated with the builtins
all the time.
The BE always gets a TFunction object and just executes it (builtins will have
an empty hdfs file location).
This removes the opcode registry and all of the functionality is subsumed by
the catalog, most of which was already duplicated there anyway.
This also introduces the concept of a system database; databases that the
user cannot modify and is populated automatically on startup.

When codegen is enabled, UDF builtins will be loaded from the IR
module rather than using the native functions. Since we cannot run
UDFs without codegen yet this means UDF builtins can only be run this
way, but once we add support for running UDFs without codegen this
will allow us to switch back to the native functions for
development/debugging.

There's a bigger change to migrate the rest of them but I think this is how
the builtins, when not running as cross compiled, should be run. This mode
is still useful when developing the builtin.
When run as cross compiled IR, we wouldn't do anything to distinguish between
a builtin and an external UDF.
