Unfortunately, toplev.c is a kitchen sink of things that do not belong anywhere
in particular. For example, check_global_declarations is only used in
cgraphunit.c. Moving it there allows us to make it static and remove one call
to symtab_node::get.
gcc/ChangeLog:
2015-09-16 Manuel López-Ibáñez <manu@gcc.gnu.org>
* toplev.h (check_global_declaration): Remove declaration.
* toplev.c (check_global_declaration): Move to ...
* cgraphunit.c: ... here. Make it static and pass a symtab_node *.
(analyze_functions): Update call.

With the new shrink-wrap algorithm, blocks reachable both with and
without prologue are duplicated, and their incoming edges are then
distributed accordingly. So we need to call fixup_partitions.

If the compiler supports split-stack but we are using a gold linker that
does not, as happens on PPC with current GCC but old gold, then we need
to compile the Go code with -fno-split-stack to avoid a linker error
avoid the inability to call from split-stack code to non-split-stack
code.

PPC has split-stack support in current GCC, but old version of gold will
reject attempts to link PPC split-stack and non-split-stack code
together. Test for that, and don't compile the C code with
-fsplit-stack if it doesn't work.
