TargetMachine::write_to_file documentation is incorrect

[programmerjake]

TargetMachine::write_to_file (wrapped and TargetMachine::write_to_memory_buffer are both functions for compiling an LLVM Module to assembly language or to machine code, writing the results to a file or to memory. They are misdocumented as being functions that write the TargetMachine to a file/memory-buffer instead of being functions to compile LLVM IR to assembly/machine code.

It might be a good idea to deprecate/remove write_to_file and write_to_memory_buffer and create new functions compile_to_file and compile_to_memory_buffer, since the write_* function names are misleading.
