  [M68k] Implement TLI::convertSelectOfConstantsToMath

This TLI callback shows the preference of other operations over
ISD::SELECT on constant operands. It's essential for M68k because
ISD::SELECT tends to lower into M68kISD::CMOV which is not always ideal.

This fixes #130754, which showed up after 352c48f278c89ac4c65642d3fadf52032e7fe734.
