Multi-byte comparison operations were used on amd64, arm64, i386 and s390x for comparisons with constant arrays, but only amd64 and i386 for comparisons with string constants. This CL combines the check for platform capability, since they have the same requirements, and also enables both on ppc64le which also supports load merging. Note that these optimizations currently use little endian byte order which results in byte reversal instructions on s390x. This should be fixed at some point.
