[CodeGen] Fix register pressure computation in MachinePipeliner (#87030) 

`RegisterClassInfo::getRegPressureSetLimit` has been changed to return a
smaller value than before so the limit may become negative in later
calculations. As a workaround, change to use
`TargetRegisterInfo::getRegPressureSetLimit`.
Also improve tests.
