3810173103 Remove IFunction::createResultColumn. 
Given that the list of supported types is hardcoded in
LLVMContext::Data::toNativeType, this method is redundant because
LLVMPreparedFunction can create a ColumnVector itself.

6b526f784c Enable the default set of LLVM optimization passes 
I honestly can't tell if they work. LLVM has surprisingly bad API documentation.

e96a5e8344 Implement JIT compilation, without a loop for now. 
It actually seems to work, so long as you only have one row that is. E.g.

    > select something(cast(number + 6 as Float64), cast(number + 2 as Float64)) from system.numbers limit 1';
    8

with this IR:

    define void @"something(CAST(plus(number, 6), 'Float64'), CAST(plus(number, 2), 'Float64'))"(void**, i8*, double*) {
    entry:
      %3 = load void*, void** %0
      %4 = bitcast void* %3 to double*
      %5 = load double, double* %4
      %6 = getelementptr void*, void** %0, i32 1
      %7 = load void*, void** %6
      %8 = bitcast void* %7 to double*
      %9 = load double, double* %8
      %10 = fadd double %5, %9
      store double %10, double* %2
      ret void
    }

b398ffbaba Map all number types to LLVM types. 
The example from the previous commit doesn't need a cast to Float64 anymore.

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.
