I've got your point.
Just for the sake of nitpicking: both your actual examples have been solved by compilers automatically.
SIMD/AVX: https://code.jsoftware.com/wiki/Guides/AVX
JVM generates vectorized string instructions from your simple for cycles - if availabe: http://jcdav.is/2016/09/01/How-the-JVM-compares-your-strings...
edit: my second example link is maybe wrong, but anyway, auto-vectorization is a real thing...
Common repeated well defined and mostly immutable code is best left as functions. This is why for example in C strcmp exists instead of everyone writing a two-liner - and the specialized variant gives big performance gains.
