[PATH] Remove xfail in const-elim-1 for ARM, PA and AIX


Hi,

While trying to see why certain tests needed XFAILing on LynxOS have
started passing now I found gcc.dg/const-elim-1.c.  The test used to
fail on certain platforms because the RTL optimizers were not able to
eliminate block moves.  The variables are no longer referenced after
tree-ssa dead code elimination so the copies are never emitted.

I checked recent ARM, HPPA and AIX testresults to check my theory and
they all XPASS this test:

http://gcc.gnu.org/ml/gcc-testresults/2005-05/msg01481.html
http://gcc.gnu.org/ml/gcc-testresults/2005-05/msg01505.html
http://gcc.gnu.org/ml/gcc-testresults/2005-05/msg01439.html

Checked with seeing if test was still passing on
i686-unknown-linux-pc.

Is the patch below OK to remove the xfail?

Adam
