[Bug translator/9770] New: stap -l 'process("bla").mark("*")' should print marker names

[mjw at redhat dot com]

Unless you know the names of the markers put into a binary it is hard to place
any probes because currently trying to list the markers with stap -l will return
the translated process("bla").statement(123456789) probe points, which don't
tell you much about what exactly will be probed.

Likewise stap -L should print argument names (and types) if possible.

[Bug translator/9770] stap -l 'process("bla").mark("*")' should print marker names

This works fine, modulo one gets a line number instead of a label name, for gcc
where there are DW_TAG_label that can be queried:
stap -c ./static_uprobes.x -l  'process("static_uprobes.x").mark("*")'
process("static_uprobes.x").function("bar@static_uprobes.c:11")
process("static_uprobes.x").function("baz@static_uprobes.c:17")
process("static_uprobes.x").function("baz@static_uprobes.c:20")
process("static_uprobes.x").function("buz@static_uprobes.c:28")
gcc compiled probes all use .label now.

This is a tough one for g++ 4.3.2 because there are usually no DW_TAG_label to
query so everything is done by converting info in .probe to .statement,
therefore there is no obvious way to hook into the -l machinery.
