Some projects need to prevent reordering of specific top level
declarations with LTO, in particular declarations defining init calls.
The only way to do that with LTO was to use -fno-toplevel-reorder,
which stops reordering for all declarations and makes LTO partitioning
less efficient.
This patch adds a new no_reorder attribute that stops reordering only
for the marked declaration. The program can then only mark e.g. the
initcalls and leave all the other declarations alone.
The patch does:
- Adds the new no_reorder attribute for the C family.
- Initializes a new no_reorder flag in the symtab_nodes in the
function visibility flag.
- Maintains the no_reorder flag when creating new nodes.
- Changes the partition code to always keep a separate
sorted queue of ordered nodes and flush them in order with the other
nodes. This is used by all nodes with -fno-toplevel-reorder,
and only the marked ones without it.
Parts of the old -fno-toplevel-reorder code paths are reused.
- Adds various checks throughout the tree to make no_reorder
marked functions behave the same as with -fno-toplevel-reorder
- Changes the LTO streamer to serialize the no_reorder attribute.

Old GDB might show short and long as short int and long int. This made
gcc.dg/guality/const-volatile.c ans restrict.c fail on older GDBs.
According to the patch that changed this in newer versions of GDB
this was a bug: https://sourceware.org/ml/gdb-patches/2012-09/msg00455.html
The patch transforms the types "short int" and "long int" coming from
GDB to plain "short" and "long". And a variant has been added to the
const-volatile.c testcase to make sure short and long long are handled
correctly now with older GDB.
gcc/testsuite/ChangeLog
* lib/gcc-gdb-test.exp (gdb-test): Transform gdb types "short int"
and "long int" to plain "short" and "long".
* gcc.dg/guality/const-volatile.c (struct bar): New struct
