This reverts commit ebb0f1d0639eeca5479fa4bfdc1ebcebf5c21dee and
follow-up commit 3c83aeee6b7d5e9ac5de1e29605ee57c2b800ca1.
These runtime callbacks are supposed to be non-instrumented,
we can't handle runtime recursion well, nor can we afford
explicit recursion checks in the hot functions (memory access,
function entry/exit).
It used to work (not crash), but it won't work with the new runtime.
Mark all runtime callbacks as non-instrumented.
