[Bug pch/19540] New: document pch directory feature

[Ralf dot Wildenhues at gmx dot de]

Please document that it is possible to store a pch of
  foo.h
in a directory named
  foo.h.gch/
such that subsequent compiles will search all files in
that directory for a good precompiled header candidate.

http://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html#Precompiled-Headers

If you need to precompile the same header file for different languages, targets, or compiler options, 
you can instead make a directory named like all.h.gch, and put each precompiled header in the 
directory, perhaps using -o. It doesn't matter what you call the files in the directory, every precompiled 
header in the directory will be considered. The first precompiled header encountered in the directory 
that is valid for this compilation will be used; they're searched in no particular order.

So this was documented already.
