  Log Message:
  -----------
  [MLIR] Generic 'malloc', 'aligned_alloc' and 'free' functions

When converted to the LLVM dialect, the memref.alloc and memref.free operations were generating calls to hardcoded 'malloc' and 'free' functions. This didn't leave any freedom to users to provide their custom implementation. Those operations now convert into calls to '_mlir_alloc' and '_mlir_free' functions, which have also been implemented into the runtime support library as wrappers to 'malloc' and 'free'. The same has been done for the 'aligned_alloc' function.
