  [MemoryBuiltins] Add getReallocatedOperand() function (NFC)

Replace the value-accepting isReallocLikeFn() overload with a
getReallocatedOperand() function, which returns which operand is
the one being reallocated. Currently, this is always the first one,
but once allockind(realloc) is respected, the reallocated operand
will be determined by the allocptr parameter attribute.
