[v3] stamp-std-precompile

This patch puts the preliminary pch bits into mainline libstdc++. Pre
compiled headers are not built by default, but can be made easily by
doing:
cd include
make stamp-std-precompile
However, things are not yet working. Oddly, making iosfwd.pch gets a
spurrious error about HAVE__BUILTIN_SIN. Also, the weird pragma
errors, already in GNATS.
New fails:
FAIL: 26_numerics/complex_value.cc (test for excess errors)
WARNING: 26_numerics/complex_value.cc compilation failed to produce executable
FAIL: 27_io/instantiations.cc (test for excess errors)
WARNING: 27_io/instantiations.cc compilation failed to produce executable
time for 'make check' with pch:
2506.113u 136.734s 46:35.61 94.5% 0+0k 0+0io 1479051pf+0w
without:
2517.154u 134.710s 49:21.78 89.5% 0+0k 0+0io 1475634pf+0w
No difference.
