[CodeGen] Preserved additional analyses in StackSlotColoring pass. (#93779)

The pass pipeline of some architecture splits register allocation phase
based on different register classes. As some analyses need to be
computed at the beginning of the register allocation and kept alive till
all values are assigned to some physical registers.

This poses challenge with objective of introducing StackSlotColoring
after partial virtual registers are assigned to physical registers, in
order to optimize stack slots usage.As this pass doesn't preserve few
analysis yet to be needed by the register allocation of the remaining
virtual registers, necessiating them to be kept preserved.
