Florian Hahn 5815f6c53c [framelowering] Skip dbg values when getting next/previous instruction. ...

Summary:
In mergeSPUpdates, debug values need to be ignored when getting the
previous element, otherwise debug data could have an impact on codegen.

In eliminateCallFramePseudoInstr, debug values after the erased element
could have an impact on codegen and should be skipped.
