Merge varpool and cgraph encoders into symtab encoders

Hi,
this patch does the boring job of merging varpool and cgraph encoders into
single symtab encoder. This has some snowballing effect. Because the IDs of
cgraphs and varpools now use single space, the cgraph and varpool sections
needs to be merged. Also reference lists output code is simplified. The
uses of encoders needs to be updated to expect all kinds of symtab nodes in
the encoder lists.
I broke out all subsequent changes from this renaming happy patch to make them
more readable.
Bootstrapped/regtested x86_64-linux and tested with Mozilla build. I will
commit it after bit of further testing. The mozilla binarry differs (due to
different UIDs) but has same size.
