Subzero: Fix build problem against LLVM trunk.

Subzero: Fix build problem against LLVM trunk.

LLVM commit 4ac35e82723d4bdbc094f73b2d33aaaa86a00d6a removed some code that Subzero still needs, specifically StreamingMemoryObject and its parents.

Deal with this by adding those files back to the Subzero repo.

This allows Subzero to build through LLVM c75e3c2fd2bb9ca010f4e1c32acbd142adc32c7f.

LGTM.

I had seen the change go by (in fact I was contacted about it). I thought it
wasn't a problem because we had copied the reader/writer for PNaCl. Hence, I
allowed the changed in LLVM. Thanks for fixing my mistaken oversight!
