fix infinite loop in instcombine with more than 4GB memcpy - memcpy size is wrongly truncated into 32-bit and treat 8GB memcpy is 0-sized memcpy - as 0-sized memcpy/memset is already removed before SimplifyMemTransfer and SimplifyMemSet in visitCallInst, replace 0 checking with assertions. - replace getZExtValue() with getLimitedValue() according to Eli Friedman git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161923 91177308-0d34-0410-b5e6-96231b3b80d8
