[tree-ssa] a few testcases

[Dan Nicolaescu <dann at ics dot uci dot edu>]

A few new testcases. 


20031216-1.c is a test for a simplification that is not done. 
ssa-ccp-11.c is a test for CCP on both the true and false side of an
if. 
sra-1.c, sra-2.c, sra-3.c are tests for SRA. 
All tests in sra-1.c pass now, they did not before SRA was
implemented, sra-2.c and sra-3.c still fail.

All the tests scan the .optimized dump. 
If they are OK, please check them in, I don't have commit access.
