libgo: reduce overhead for memory/block/mutex profiling

    Revise the gccgo version of memory/block/mutex profiling to reduce
    runtime overhead. The main change is to collect raw stack traces while
    the profile is on line, then post-process the stacks just prior to the
    point where we are ready to use the final product. Memory profiling
    (at a very low sampling rate) is enabled by default, and the overhead
    of the symbolization / DWARF-reading from backtrace_full was slowing
    things down relative to the main Go runtime.

Add __is_nothrow_convertible to fix std::is_nothrow_invocable_r

The definition of is_nothrow_invocable in terms of is_convertible and
is_nothrow_constructible is incorrect, because a type could have an
explicit constructor that means is_nothrow_constructible is true, but
implicit conversions could use a different constructor that is
potentially-throwing.

only considers implicit conversions.

Make std::match_results::_M_resize more useful

As both callers of match_results::_M_resize(unsigned) immediately follow
it with a loop to update the value of each sub_match, that behaviour can
be moved into _M_resize itself. The first caller fills the container
with unmatched subs, which can be done with vector::assign, and the
second caller clears the container to establish a specific state, which
can be provided by a new member function specific to that purpose.

Tangentially, I also noticed that match_results::max_size() doesn't
account for the three special sub_match objects that are always present
in a fully established result state. This patch also fixes that.
