Author: Stan Cox <scox@redhat.com>

Add debuginfoless static uprobe handling.
The .probes section now contains the assembler asm equivalent of each
probe argument. stap parses this and generates the equivalent stap code
to access each argument.
* sdt.h (stap_sdt_probe_entry_v1): New.
(stap_sdt_probe_entry_v2): New.
(STAP_SDT_V1,STAP_SDT_V2): New.
(__stap_argN,STAP_PROBE_POINT): New.
* tapsets.cxx (sys/sdt.h,regex.h): Include.
(sdt_uprobe_var_expanding_visitor,sdt_kprobe_var_expanding_visitor):
Split from sdt_var_expanding_visitor.
(sdt_uprobe_var_expanding_visitor::visit_target_symbol): Convert
$argN into the equivalent asm argument then expand into equivalent
stap parse tree.
(sdt_query): Add arg_count, pc, arg_string, have_uprobe, have_kprobe
(sdt_query::handle_query_module): Handle uprobe2_type.
(sdt_query::get_next_probe): Likewise.
* sdt_misc.exp (pbtype_flags): Add -DSTAP_SDT_V2
(Test 7): Add to test types defined in *.d.
