wildmatch: make a special case for "*/" with FNM_PATHNAME
Normally we need recursion for "*". In this case we know that it
matches everything until "/" so we can skip the recursion.
glibc, '*/*/*' on linux-2.6.git file list 2000 times
before:
wildmatch 8s 74513us
fnmatch 1s 97042us or 13.59% faster
after:
wildmatch 3s 521862us
fnmatch 3s 488616us or 99.06% slower
Same test with compat/fnmatch:
wildmatch 8s 110763us
fnmatch 2s 980845us or 36.75% faster
wildmatch 3s 522156us
fnmatch 1s 544487us or 43.85% slower
