Florian Hahn 64cf7359d3 [SCCP] Move tests using only ipsccp from IPConstantProp to SCCP (NFC).
Some of the tests in the llvm/test/Transforms/IPConstantProp directory
actually only use -ipsccp. Those tests belong to the other (IP)SCCP
tests in llvm/test/Transforms/SCCP/ and this commits moves them there to
avoid confusion with IPConstantProp.
