Javascript - avoid replaceAll

This is a kind of specific case, but the generated javascript prints $ while the original semantics was to print $$. This is caused by replaceAll interpreting the $ in the replacement string as capture groups, even when the search is not a regex. So it can actually only be used when the replacement is a text literal that doesn't contain a dollar. Otherwise the split + join trick should be used.
Alternatively, we could add a flag to the Text type (could also be useful for shorter replacement code in Lua) but that seems like an overkill.
