Lang Hames 72d195ecf0 [ORC] Update ORC C bindings to use the new llvm::Error C API. 
This replaces instances of the LLVMOrcErrorCode type with LLVMErrorRef,
simplifying the implementation of the OrcCBindingsStack class and ORC
C API bindings and making it possible to return arbitrary (wrapped)
llvm::Errors.

Lang Hames 00fb14da27 [Support] Add a basic C API for llvm::Error. 
Summary:
The C-API supports consuming errors, converting an error to a string error
message, and querying an error's type. Other LLVM C APIs that wish to use
llvm::Error can supply error-type-id checkers and custom
error-to-structured-type converters for any custom errors they provide.
