Add experimental utrace/kprobe sdt support

* sdt.h (EXPERIMENTAL_UTRACE_SDT, EXPERIMENTAL_KPROBE_SDT): New probe
point macros.
* dtrace: Add support for creating type debug info, currently invoked
with --types.
* tapsets.cxx (probe_table::convert_probe): New.
(probe_table::convert_location): New.
(dwarf_builder::build):  Use it to simplify probe point handling.
* sdt.exp (pbtype_flags, pbtype_mssgs): New to also test kprobe and utrace.
* static_uprobes.exp (pbtype_flags, pbtype_mssgs): New to also test kprobe and utrace.
