Currently there is no direct way. For edges and signals, it may
be possible to support this by making sure that certain
attributes (e.g. 'negedge') can be checked in code. But that
is not possible currently (that is, it won't work as expected).
For other things, such as delays, it's not clear how to do it.

However, do we actually need this?
For synthesizable code, the classic synthesis templates are such
that the relevant checks are done implicitly by the
top-level if-then-else structure.

For non-synthesizable code, you have the option of using
separate always blocks, each triggered by the relevant condition.
