[Committed] Add some more testcases

[Andrew Pinski]

Hi,
  While looking at what patches I had in the internal tree here at
Cavium, I noticed two more testcases which I did upstream already.
One testcase for PR 53135 (reduced from dhcp-server) and another one
for an ICE which showed up while improving PHI-OPT (reduced from
gnupg-2.0.18).

Committed as obvious after a test.

Thanks,
Andrew

ChangeLog:
* gcc.c-torture/compile/20120927-1.c: New testcase.
* gcc.c-torture/compile/20120830-1.c: New testcase.
