01f43a4d55 Add the majority of machine-level critical edge breaking pass. Most of this was written by Fernando, cleanup and updating to TOT by me. 
This still needs a bit of work, particularly to handle jump tables properly.

43b665db50 Revised BatchEmitOwnedPtrs to work better with constant pointers.

6d0372d0b3 Revised implementation of BatchReadOwnedPtrs() that deserializes an 
array of pointers to not allocate a second array to contain the pointer ids.

Fixed bug in the same member function where deserialized pointers were
not being registered with the backpatcher.

6d8ab4ae81 Added methods to batch emit and deserialize owned pointers. This allows 
to group the pointer IDs together in the bitstream before their referenced
contents (which will lend itself to more efficient encoding).

4542edcaa7 Complete conditionalization of Dwarf reg numbers. 
Would somebody not on Darwin please make sure this
doesn't break anything.  Exception handling failures
would be the most likely symptom.

18b5ddb5bf Added special version of ReadPtr() that returns a deserialized pointer 
by value.  This version prohibits backpatching of pointers, so it
useful when a pointee is always known to be deserialized beforehand.
