Derek Schuff fcfd5ae82c Fix StreamingMemoryObject to respect known object size. 
The existing code for method StreamingMemoryObject.fetchToPos does not respect
the corresonding call to setKnownObjectSize(). As a result, it allows the
StreamingMemoryObject to read bytes past the object size.

This patch provides a test case, and code to fix the problem.

Aaron Ballman af93cd8de9 Fixing -Wtype-limits warnings with the asserts (the expression would always evaluate to true). Also fixing a -Wcast-qual warning, where the cast expression isn't required.

Rafael Espindola c11bd4229c Read 64 bits at a time in the bitcode reader. 
The reading of 64 bit values could still be optimized, but at least this cuts
down on the number of virtual calls to fetch more data.

Rafael Espindola 0c9aa57a07 Use the return of readBytes to find out if we are at the end of the stream. 
This allows the removal of isObjectEnd and opens the way for reading 64 bits
at a time.

Rafael Espindola 2d05db49bb Return the number of read bytes in MemoryObject::readBytes. 
Returning more information will allow BitstreamReader to be simplified a bit
and changed to read 64 bits at a time.

Rafael Espindola 79e1f9ff99 Merge StreamableMemoryObject into MemoryObject. 
Every MemoryObject is a StreamableMemoryObject since the removal of
StringRefMemoryObject, so just merge the two.

I will clean up the MemoryObject interface in the upcoming commits.
