66da9f38 - [SelectionDAG] Fix copyExtraInfo where new node has entry as operand (#149307)

[SelectionDAG] Fix copyExtraInfo where new node has entry as operand (#149307) Add special case handling where a new replacement node has the entry node as an operand i.e. does not depend on any other nodes. This can be observed with the existing X86/pcsections-atomics.ll test case when targeting Haswell, where certain 128-bit atomics are transformed into arch-specific instructions, with some operands having no other dependencies.
