Updated patch

This patch will tolerate the failure for optional probe in derive_probe as
Frank mentioned in comment #6. Seems all the probe types can be covered.

$ stap -p2 -ue 'probe foo?, process("/do/not/exist").function("main") !,
kernel.mark("no such mark") ?, kernel.trace("no trace") !, process.foo ?,
kernel.statement("no statement") !, module("no mod").function("*") ?, begin {}'

# probes
begin /* <- foo?,process("/do/not/exist").function("main")!,kernel.mark("no
such mark")?,kernel.trace("no trace")!,process.foo?,kernel.statement("no
statement")!,module("no mod").function("*")?,begin */
