All the parameters are documented in the manual. Many of them are
tradeoffs among the areas you mention.

As far as I know, the only language-specific parameter is
cxx-max-namespaces-for-diagnostic-help. As far as I know, there are
no architecture-specific parameters, though it may be worth mentioning
that several of the backends do set default values for parameters like
l1-cache-size.
