    PR11340: Use local vardecls for tracepoint/marker args
    
    This gets rid of the "probe_context_var" field of target_symbols, which
    was a hacky way to resolve args into a special local variable.  Now we
    create a real local vardecl and mark it with "skip_init" so we know that
    it will be filled in by derived_probe-specific code.
    
    * staptree.h (target_symbol): Remove probe_context_var.
      (vardecl): Add skip_init.
    * elaborate.h (derived_probe::emit_probe_context_vars): Remove, as such
      vars are now emitted along with all the other locals.
    * elaborate.cxx (semantic_pass_opt2): Make skip_init locals immune to
      read/write analysis.
      (const_folder::visit_defined_op): No more probe_context_var.
      (typeresolution_info::visit_symbol): Ditto.
    * tapset-mark.cxx (mark_var_expanding_visitor::visit_target_symbol_arg):
      Refer to the local name as a normal symbol reference.
      (mark_derived_probe::mark_derived_probe): If target_symbols were used,
      add vardecls to the probe locals.
      (mark_derived_probe::emit_probe_context_vars): Remove.
    * tapsets.cxx (var_expanding_visitor::visit_defined_op): For @defined,
      there's no longer a "success" via probe_context_var.
      (tracepoint_var_expanding_visitor::visit_target_symbol_arg): Refer to
      the local name as a normal symbol reference.
      (tracepoint_derived_probe::tracepoint_derived_probe): For each used
      arg, add a vardecl to the probe locals.
      (tracepoint_derived_probe::emit_probe_context_vars): Remove.
    * translate.cxx (c_unparser::emit_common_header): No probe_context_vars.
      (c_unparser::emit_probe): Don't init the skip_init locals.
      (c_unparser_assignment::visit_symbol): No more probe_context_var.
