libstdc++: Use constexpr-if to slightly simplify <regex>
This will hardly make a dent in the very slow compile times for <regex>
but it seems worth doing anyway.
libstdc++-v3/ChangeLog:
* include/bits/regex_compiler.h: Replace _GLIBCXX17_CONSTEXPR
with constexpr and disable diagnostics with pragmas.
(_AnyMatcher::operator()): Use constexpr-if instead of tag
dispatching. Postpone calls to _M_translate until after checking
result of earlier calls.
(_AnyMatcher::_M_apply): Remove both overloads.
(_BracketMatcher::operator(), _BracketMatcher::_M_ready):
Replace tag dispatching with 'if constexpr'.
(_BracketMatcher::_M_apply(_CharT, true_type)): Remove.
(_BracketMatcher::_M_apply(_CharT, false_type)): Remove second
parameter.
(_BracketMatcher::_M_make_cache): Remove both overloads.
* include/bits/regex_compiler.tcc (_BracketMatcher::_M_apply):
Remove second parameter.
* include/bits/regex_executor.tcc: Replace _GLIBCXX17_CONSTEXPR
with constexpr and disable diagnostics with pragmas.
(_Executor::_M_handle_backref): Replace __glibcxx_assert with
static_assert.
(_Executor::_M_handle_accept): Mark _S_opcode_backref case as
unreachable for non-DFS mode and do not instantiate
_M_handle_backref for that case.
