[lto]: patch committed to get flags and line numbers correct.

[Kenneth Zadeck]

This patch fixes more cases where some of the flags were not being set
in compatible ways.  it also finishes the code to get line numbers put
out in a compatible way.  The code USE_MAPPED_LOCATION has still not
been tested, but will be done after the next merge.

The code also adds a new tree dump flag, -fdump-tree-*-verbose.  This
does a regular tree dump for a statement after the statement is
printed.  The tree dumps are a lot more detailed and so allow the
checking that all of the tree information has been properly serialized.

committed as revision 130095.
