Define new filesystem::__file_clock type

In C++17 the clock used for filesystem::file_time_type is unspecified,
allowing it to be chrono::system_clock. The C++2a draft requires it to
be a distinct type, with additional member functions to convert to/from
other clocks (either the system clock or UTC). In order to avoid an ABI
change later, this patch defines a new distinct type now, which will be
used for std::chrono::file_clock later.

(file_time_type): Redefine in terms of __file_clock.

runtime: prevent deadlock when profiling signal arrives during traceback

    Traceback routines, e.g. callers and funcentry, may call
    __go_get_backtrace_state. If a profiling signal arrives while we
    are in the critical section of __go_get_backtrace_state, it tries
    to do a traceback, which also calls __go_get_backtrace_state,
    which tries to enter the same critical section and will deadlock.
    Prevent this deadlock by setting up runtime_in_callers before
    calling __go_get_backtrace_state.

    Found while investigating golang/go#29448. Will add a test in the
    next CL.

Export explicit instantiations for C++17 members of std::string

The C++17 standard added some new members to std::basic_string, which
were not previously instantiated in the library. This meant that the
extern template declarations had to be disabled for C++17 mode. With
this patch the new members are instantiated in the library and so the
explicit instantiation declarations can be used for C++17.

Fix bugs in filesystem::path::lexically_normal()

Using path::_List::erase(const_iterator) to remove a non-final component
in path::lexically_normal() is a bug, because it leaves the following
component with an incorrect _M_pos value.

Instead of providing erase members that allow removing components from
the middle, replace them with pop_back() and
_M_erase_from(const_iterator) which only allow removing elements at the
end. Most uses of erase are unaffected, because they only remove
elements from the end anyway. The one use of erasure from the middle in
lexically_normal() is replaced by calls to pop_back() and/or clearing
the last component to leave it as an empty final filename.

Add more testcases for class template argument deduction of maps

This adds additional tests for std::map and std::multimap CTAD. The
tests ensure that deduction works for braced-init-list of value_type
objects, and for pairs of input iterators (with both std::pair<Key, T>
and value_type as the iterator's value_type). This ensures deduction
from value_type still works, as well as the non-value_type cases in LWG
3025.

Similar tests for unordered maps do not work, apparently because the
constructor taking an initializer_list<value_type> is not usable for
deduction, and the deduction guide taking initializer_list<pair<Key, T>>
deduces key_type to be const. I am not addressing that.
