vim-patch:9.2.1100: NFA regexp engine does not inline copy_sub()
Problem: copy_sub() is on the hottest path of the NFA regexp engine, since
addstate() calls it for every state it adds, but at -O2 the
compiler leaves it out of line so every call pays function-call
overhead.
Solution: Mark copy_sub() "static inline" so the compiler folds it into its
callers, which slightly increases binary size.
Measured over a buffer of C code, regexp search and substitute are
about 6-8% faster, including patterns with capturing groups.
