 Hi Brent, Hi Sebastian,

this is already done by this PR https://github.com/php/php-src/pull/5913

The options to talk about and use in docs/posts are the following:

opcache.jit=yes|true|1
opcache.jit=tracing
opcache.jit=function

These differentiate the Tracing-JIT from the Function-JIT. Default is
tracing.
