Using specific SSA names in pattern matching in `dg-final' makes tests
"unstable", in that changes in passes prior to the pass whose dump is
analyzed in the particular test may change the numbering of the SSA
variables, causing the test to start failing spuriously.
We thus switch from specific SSA names to the use of a multi-line
regular expression making use of capture groups for matching particular
variables across different statements, ensuring the test will pass
more consistently across different versions of GCC.

Yea, we definitely should not be using specific SSA_NAME versions in a
testcase like that.
OK for the trunk. Please go ahead and install.
Thanks!
