[InstCombine] Support vectors in SimplifyAddWithRemainder.
SimplifyAddWithRemainder currently also matches for vector types, but
tries to create an integer constant, which causes a crash.
By using Constant::getIntegerValue() we can support both the scalar and
vector cases.
The 2 added test cases crash without the fix.
