New Revision: 184532

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=184532
Log:
This patch writes the tree header for mutated trees.  This write is
necessary to get updated attribute information from the info bits.
On read, these bits are then merged into the existing tree.

Test x2incomplete4.cc is now generating assembly.  However, it
erroneously generates an inline default constructor.  This error
likely occurs because pph_in_symtab actions are handled after reading
each pph file, rather merged and emitted after all pph files are read.
Diego will address this symtab merge.

Since we are now merging types, this patch includes a fix to more
aggressively trace types.

In addition, there are a couple of fixes to protect against null
pointers.

Tested on x64.
