[llvm-commits] Proposal/patch: Enable bitcode streaming

Attached is patch 1 as listed above: a refactor of BistreamCursor to use an
offset rather than raw pointers, and abstract the relevant operations into
functions. For now BitstreamReader is the same. I've tested it locally and
it works in isolation and is hopefully ready to apply. Patch 2, a subclass
of MemoryObject (StreamableMemoryObject) to replace the BitstreamBytes
class here, is upcoming next.

thanks,
