PR fortran/91413 Generate warning when making array static
When moving a local variable from the stack to static storage, the
procedure is no longer safe to be called recursively or concurrently
from multiple threads. Thus generate a warning when this is done.
Also double the default limit for switching from stack to static.
Regtested on x86_64-pc-linux-gnu.
