bug#13605: 24.3.50; Eager macro-expansion failure: (void-variable ruby-syntax-methods-before-regexp) when ruby-mode is not compiled

[Dmitry Gutov]

This applies both to trunk and emacs-24.

ruby-mode compiles without warnings, and ruby-syntax-propertize-function
works fine either way, but when ruby-mode is not compiled, it shows the
subject warning upon loading, and ruby-syntax-propertize-function is an
order of magnitude slower (not very noticeable in the simple cased, though),
due to syntax-propertize-rules not being expanded.

The constant in question is defined in an `eval-and-compile' block, I
can't see what else could the interpreter need. Help?
