[RFC] Dump function attributes

[Tom de Vries]

Hi,

patch below prints the function attributes in the dump file.

Say we mark a function foo with attributes noinline and noclone like this:
...
int __attribute__((noinline, noclone))
foo (void)
...

Then using this patch, we find in the dump file:
...
;; Function foo (foo, funcdef_no=10, decl_uid=2455, cgraph_uid=10, 
symbol_order=10)

Pass statistics of <pass>: ----------------

foo ()
[ noclone , noinline ]
{
...

Good idea?

If so, do we want one attribute per line?

Thanks,
- Tom
