Lang Hames 39f64c4c83 [ORC] Add wrapper-function support methods to ExecutorProcessControl. 
Adds support for both synchronous and asynchronous calls to wrapper functions
using SPS (Simple Packed Serialization). Also adds support for wrapping
functions on the JIT side in SPS-based wrappers that can be called from the
executor.

These new methods simplify calls between the JIT and Executor, and will be used
in upcoming ORC runtime patches to enable communication between ORC and the
runtime.

Lang Hames 4eb9fe2e1a [ORC] Port WrapperFunctionUtils and SimplePackedSerialization from ORC runtime. 
Replace the existing WrapperFunctionResult type in
llvm/include/ExecutionEngine/Orc/Shared/TargetProcessControlTypes.h with a
version adapted from the ORC runtime's implementation.

Also introduce the SimplePackedSerialization scheme (also adapted from the ORC
runtime's implementation) for wrapper functions to avoid manual serialization
and deserialization for calls to runtime functions involving common types.
