Protect all run-time checks and supporting machinery with "if

pragma Suppress or -gnatp.
Add Pseudo_Reference and Get_Element_Access to remaining

builtins-20.c had:
if (cos((y*=2, -fabs(tan(x/-y)))) != cos((y*=2,tan(x/y))))
link_error ();
which is undefined behaviour. The test expected that y had the same
value in x/y and x/-y, but gimplification actually implements the
"obvious" interpretation, multiplying y by 2, using it for one cos call,
then multiplying it by 2 again and using it for the other cos call.
The file has other (valid) tests that side-effects don't block
optimisation, such as:
if (cosf((y*=3, -x)) != cosf((y*=3,x)))
link_error ();
so this patch simply removes this instance.

Fix an inconsistent state, between the in_common attribute
and the common_block pointer.
- adding a symbol to a common block list in gfc_match_common is delayed
after the call to gfc_add_in_common.
- gfc_restore_latest_undo_checkpoint is changed to check the common_block
pointer directly instead of the in_common attribute.
- gfc_restore_old_symbol is changed to also restore
the common-related pointers. This is done using a new function created
to factor the related memory management.
- In gfc_restore_last_undo_checkpoint, when a symbol has been removed
from the common block linked list, its common_next pointer is cleared.
