Some tests failed for NVPTX target, but it seems that NVPTX will be
fixed and the tests will pass. So, just mark the tests as XFAIL

Summary:
During icmp lowering it can happen that a constant value can be larger than expected (see the code around the change).
APInt::getMinSignedBits() must be checked again as the shift before can change the constant sign to positive.
I'm not sure it is the best fix possible though.
Test Plan: Regression test included.
