Update comments in QString about alignment performance.
This commit makes no code change at all.
Write down the conclusions from experimenting with the x86 SIMD
instructions for faster string comparison routines. Long story short:
we're already pretty good.
The SSE4.2 string instructions are probably more useful for
"implicit-length mode" (that is, the end of the string is marked by a
NUL), rather than QString's "explicit-length mode".
