Fix a heinous inefficiency introduced in r149918, wherein reading each byte of a
...
BLOB (i.e., large, performance intensive data) in a bitcode file was switched to
invoking one virtual method call per byte read. Now we do one virtual call per
BLOB.

wean Blob handling logic off of banging on NextChar directly. Instead, make
...
it reason about the current bit position, which is always independent of the
underlying cursors word size.

Add a new BitstreamEntry concept, and add two helper methods for walking
...
through a BitstreamCursor that produce it: advance() and
advanceSkippingSubblocks(), representing the two most common ways clients
want to walk through bitcode.

BitstreamReader hasn't aged well. It's been hacked on by various people and

has past the point of making sense. Lets tidy things up: first step, moving
a ton of big functions out of line.
