2d15a52df0 Implement PR1786 by iterating between dead cycle elimination 
and simplifycfg in the rare cases when it is needed.

cc75435ebf Unify CALLSEQ_{START,END}. They take 4 parameters: the chain, two stack 
adjustment fields, and an optional flag. If there is a "dynamic_stackalloc" in
the code, make sure that it's bracketed by CALLSEQ_START and CALLSEQ_END. If
not, then there is the potential for the stack to be changed while the stack's
being used by another instruction (like a call).

This can only result in tears...

960f531bbe Added versions of ReadPtr that takes an explicit SerializedPtrID. This allows 
clients of the Deserializer to read the pointer ID before they are ready
to deserialize the object (which can mean registering a pointer reference
with the backpatcher).

Changed some methods that took an argument "SerializedPtrID" to "const SerializedPtrID&" (pass-by-reference).  This is to accommodate a future
revision of SerializedPtrID where it may be much fatter than an unsigned
integer.

to be a pass of its own.  Instead, move it out into a helper method.

8e8473c783 Use TableGen to emit information for dwarf register numbers. 
This makes DwarfRegNum to accept list of numbers instead.

72b9e78ab1 Fixed hack in BatchReadOwnedPtrs to no longer use the array of pointers passed in for 
deserialization as a temporary location for storing serialized pointer identifiers. The
definition of SerializedPtrID will likely change significantly in the future, and the
current implementation caused compilation errors on some 64-bit machines.

107cb494e2 Added "random access" to the Deserializer to allow a client to jump to any 
serialized block in the bitstream, including a block in an entirely different
nesting than the current block. This is useful for deserializing objects from
a bitstream in an order different from the order that they were serialized.

93329cbed2 Made Deserializer a friend class of BitstreamReader. 
Moved some of the logic in BitstreamReader::ExitBlock into a utility function
BitstreamReader::PopBlockScope. The latter is a private method. It will also
be called by Deserializer to manipulate the current "block scope."
