/* Save the definition of a single macro, so that it will persist
across a PCH restore. Because macro data is in GCed memory, which
will be blown away by PCH, it must be temporarily copied to
malloced memory. (The macros will refer to identifier nodes which
are also GCed and so on, so the copying is done by turning them
into self-contained strings.) The assumption is that most macro
definitions will come from the PCH file, not from the compilation
before the PCH file is loaded, so it doesn't matter that this is
a little expensive.
It would reduce the cost even further if macros defined in the PCH
file were not saved in this way, but this is not done (yet), except
for builtins, and for #assert by default. */
