patch 9.1.1184: Unnecessary use of vim_tolower() in vim_strnicmp_asc()
Problem: Unnecessary use of vim_tolower() in vim_strnicmp_asc().
Solution: Use TOLOWER_ASC() instead (zeertzjq).
It was passing *s1 and *s2 to vim_tolower(). When char is signed, which
is the case on most platforms, c < 0x80 is always true, so it already
behaves the same as TOLOWER_ASC().
