Florian Hahn 294f3becd3 [ConstantFold] Use getMinSignedBits for APInt in isIndexInRangeOfArrayType.
Indices for getelementptr can be signed so we should use
getMinSignedBits instead of getActiveBits here. The function later calls
getSExtValue to get the int64_t value, which also checks
getMinSignedBits.

This fixes  https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=11647.
