f9bee1e089 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.

0daf840e56 Removed debug #define that was accidentally checked in while debugging 
the deserializer.

Fixed assertion when "stream jumping" in the deserializer to properly function
when we have reached the end of the stream.

e6821dd990 Eliminate the recently introduced CCAssignToStackABISizeAlign 
in favour of teaching CCAssignToStack that size 0 and/or align
0 means to use the ABI values.  This seems a neater solution.
It is safe since no legal value type has size 0.

fd33cb316f 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.

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.
