[ConstantFold] ExtractConstantBytes - handle shifts on large integer types

Use APInt instead of getZExtValue from the ConstantInt until we can confirm that the shift amount is in range.

Reduced from OSS-Fuzz #14169 - https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=14169

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@358192 91177308-0d34-0410-b5e6-96231b3b80d8
