-------------------------------------------
As part of my PR, I'm adding more benchmarks to gandiva/benchmarks.cc - this'll
exercise both the arrow-decimal code and gandiva-decimal code.
> [Gandiva] Add support for decimal operations

> To begin with, will add support for 128-bit decimals. There are two parts :
> # llvm_generator needs to understand decimal types (value, precision, scale)
> # code decimal operations : add/subtract/multiply/divide/mod/..
> ** This will be c++ code that can be pre-compiled to emit IR code
