bug#13764: 24.3.50; please do not use defsubst for `font-lock-(apply-highlight|fontify-anchored-keywords)'

[Drew Adams]

These are not tiny, trivial functions.
 
They do not fit the criteria for `defsubst' outlined in (elisp)
`Inline Functions'.  And they introduce all of the disadvantages
listed there, especially this one, listed first:
 
  [I]f you change the definition of the function, calls already
  inlined still use the old definition until you recompile them.
 
One use case: I have highlighting code that uses text property
`font-lock-ignore'.  I modify a few font-lock.el functions so that text
that has this property is ignored.  IOW, this property tells font-lock
"Hands off", so that it will not erase of otherwise interfere with such
highlighting.
 
I see no reason why these function should not be defuns.
