Mikael Holmen 97e16560aa [MemoryBuiltins] Allow truncation in visitAllocaInst() ... Summary: Solves PR33689. If the pointer size is less than the size of the type used for the array size in an alloca (the <ty> type below) then we could trigger the assert in the PR. In that example we have pointer size i16 and <ty> is i32. <result> = alloca [inalloca] <type> [, <ty> <NumElements>] [, align <alignment>] Handle the situation by allowing truncation as well as zero extension in ObjectSizeOffsetVisitor::visitAllocaInst(). Also, we now detect overflow in visitAllocaInst(), similar to how it was already done in visitCallSite().
