tapsets.cxx (sdt_uprobe_var_expanding_visitor): Moved register lookup table 
into the translator.
(sdt_uprobe_var_expanding_visitor::visit_target_symbol): Properly handle v1 
uprobes.  Use fetch_register to fetch arguments

sdt.h (STAP_SDT_V1):  Define if host isn't x86.
(args1, ..., args10):  Variadic macro is cleaner, but unfortunately gets -ansi 
-pedantic warning
