This avoids a possible crash when inlining a SRF whose argument list contains a reference to an inline-able user function. The crash is quite reproducible with CLOBBER_FREED_MEMORY enabled, but would be less certain in a production build. Problem introduced in 9.0 by the named-arguments patch, which requires invoking eval_const_expressions() before we can try to inline a SRF. Per report from Brendan Jurd.
