[Bug libstdc++/28277] New: __builtin_alloca with no limit in libstdc++

[mec at google dot com]

libstc++ uses __builtin_alloca in several places:

  config/local/gnu/codecvt_members.cc
  include/ext/codecvt_specializations.h
  include/ext/vstring.cc
  include/bits/locale_facets.tcc
  include/bits/ostream.tcc
  include/bits/fstream.cc
  include/std/std_valarray.h
  src/valarray-inst.cc

These have data-dependent sizes with no obvious limit, which does not mix well
with threads and small stacks.
