93c65108de Revised BatchEmitOwnedPtrs to work better with constant pointers.

eaafbccdd8 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.

076d1903ec Fixed bug where we did not properly serialize owned objects due to a missing 
dereference.

an array of pointers of the same type.

28ffec0b56 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).

b11aca8a92 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.

ac282bd929 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.

c401482711 When the allocator rewrite a spill register with new virtual register, it replaces other operands of the same register. Watch out for situations where 
only some of the operands are sub-register uses.

59b08debe3 At the point of calculating the shift amount, the 
type of SV has changed from what it originally was.
However we need the store width of the original.

3764ad2bac Add pseudo dependency to force two-address instruction to be scheduled after
