* call.c (build_this_conversion): New function, split out from
add_function_candidate.
(add_function_candidate): New parameter shortcut_bad_convs.
Document it. Use build_this_conversion. Stop at the first bad
argument conversion when shortcut_bad_convs is true.
(add_template_candidate_real): New parameter shortcut_bad_convs.
Use build_this_conversion to check the 'this' conversion before
attempting deduction. When the rejection reason code is
rr_bad_arg_conversion, pass -1 instead of 0 as the viable
parameter to add_candidate. Pass 'convs' to add_candidate.
(add_template_candidate): New parameter shortcut_bad_convs.
(add_template_conv_candidate): Pass false as shortcut_bad_convs
to add_template_candidate_real.
(add_candidates): Prefer to shortcut bad conversions during
overload resolution under the assumption that we'll eventually
see a strictly viable candidate. If this assumption turns out
to be false, re-process the non-strictly viable candidates
without shortcutting those bad conversions.
