IR, Bitcode: Change bitcode reader to no longer own its memory buffer.

Unique ownership is just one possible ownership pattern for the memory buffer

often reside at a higher level. With the upcoming change to allow multiple

modules to generally have unique ownership of their memory buffer.

The C API exposes the ownership relation via the LLVMGetBitcodeModuleInContext

the module to own the memory buffer. This patch does so by adding an owned
