86f462acff Support unaligned array join 
For left ARRAY JOIN, expand to the greatest size. If all sizes are zero,
resize to one which is the same as the old behavior, i.e. emptyArrayToSingle

For non-left ARRAY JOIN, expand to the greatest size but keep empty if all sizes are zero.

65b654a1b6 Versatile StorageJoin 
This commit does the following:

1. StorageJoin with simple keys now supports reading
2. StorageJoin can be created with Join settings applied. Syntax is
similar to MergeTree and Kafka
3. Left Any StorageJoin with one simple key can be used as a
dictionary-like structure by function joinGet.

Examples are listed in the related test file.

851684de51 Add a JIT interface for row-wise default-nullable functions. 
Not actually implemented, though. It does print out some jit-compiled stuff,
but that's about it. For example, this query:

    select number from system.numbers where something(cast(number as Float64)) == 4

results in this on server's stderr:

    define double @"something(CAST(number, 'Float64'))"(void**, i8*, void*) {
    "something(CAST(number, 'Float64'))":
      ret double 1.234500e+04
    }

(and an exception, because that's what the non-jitted method does.)

As one may notice, this function neither reads the input (first argument;
tuple of arrays) nor writes the output (third argument; array), instead
returning some general nonsense.

In addition, `#if USE_EMBEDDED_COMPILER` doesn't work for some reason,
including LLVM headers requires -Wno-unused-parameter, this probably only
works on LLVM 5.0 due to rampant API instability, and I'm definitely
no expert on CMake. In short, there's still a long way to go.
