[Bug fortran/44773] [4.6 Regression] Unnecessary temporaries increase the runtime for channel.f90 by ~70%

[dominiq at lps dot ens dot fr]

------- Comment #15 from dominiq at lps dot ens dot fr  2010-07-09 12:02 -------
The patch in comment #10 avoids the extra temporaries and recovers the original
timings. Regstrapped without regression and passed my tests. Note also that it
"fixes" pr44744.

Concerning the test in comment #13 it gives 3.0 with/without the patch (as well
with g95). I don't know if it should give 1.0 (the value before "call bar(u)")
or not, but the result does not depend on the patch.

Thanks for the quick fix.
