Mehdi Amini 15e1e7f179 Remove access to the DataLayout in the TargetMachine
Summary:
Replace getDataLayout() with a createDataLayout() method to make
explicit that it is intended to create a DataLayout only and not
accessing it for other purpose.

This change is the last of a series of commits dedicated to have a
single DataLayout during compilation by using always the one owned
by the module.

//                 Kaleidoscope with Orc - Lazy IRGen Version
//===----------------------------------------------------------------------===//

This version of Kaleidoscope with Orc demonstrates lazy IR-generation.
Building on the lazy-codegen version of the tutorial, this version reduces the
amount of up-front work that must be done by lazily IRgen'ing ASTs. When a
function definition is entered, its AST is added to a map of available
definitions. No IRGen is performed at this point and nothing is added to the JIT.
When attempting to resolve symbol addresses, the lambda in
KaleidoscopeJIT::getSymbolAddress will scan the AST map and generate IR on the
fly.

This directory contains a Makefile that allows the code to be built in a
standalone manner, independent of the larger LLVM build infrastructure. To build
the program you will need to have 'clang++' and 'llvm-config' in your path.
