65e2da3b4d Fix handling of overflow in loop calculation by adding new UDiv SCEV. This SCEV
is disabled in the sense that it will refuse to create one from a UDiv
instruction, until the code is better tested.

7c6ad0c06e Fixed serious bug in BatchReadOwnedPtrs where in a chain of calls to
deserialize objects if BatchReadOwnedPtrs was called more than once in the
same call chain then the second call would overwrite the SerializedPtrIDs
being used by the first call. Solved this problem by making the vector that
holds the pointer IDs local to a function call. Now BatchReadOwnedPtrs is
reentrant.

c498b0281f Clean up sub-register implementation by moving subReg information back to
MachineOperand auxInfo. Previous clunky implementation uses an external map
to track sub-register uses. That works because register allocator uses
a new virtual register for each spilled use. With interval splitting (coming
soon), we may have multiple uses of the same register some of which are
of using different sub-registers from others. It's too fragile to constantly
update the information.

0f8d9c04d9 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...

62724da930 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.

303f7fe149 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.

1a8a08a690 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.

13faf5c13c 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."

48a396948f Updated Deserializer class to provide more information about the current
block that is being visited in the bitstream.  The client can also now
skip blocks before reading them, and query the current abbreviation number
as seen from the perspective of the Deserializer.  This allows the client
to be more interactive in the deserialization process (if they so choose).

ec8cd06555 Added typedef "SerializedPtrID" to represent the pointer handle written to disk
instead of just using "unsigned".  This gives us more flexibility in changing
the definition of the handle later, and is more self-documenting.

Added tracking of block stack in the Deserializer.  Now clients can query
if they are still within a block using the methods GetCurrentBlockLocation()
and FinishedBlock().
