Where's the Steengaard stuff supposed to go?

[Steven Bosscher]

Daniel,

I cannot build G95 anymore since you commited the Steengaard alias
analysis stuff. If I link to tree-alias-steen.o, I get a number of
errors about a missing function 'create_tmp_alias_var()', and if I don't
link to it, I get a missing function error from tree-optimize.o for the
same function (this used to work).

I tought these optimizers were supposed to work on SIMPLE, so why is
this function specific to C? If it's not, can't you move all functions
etc related to them to a separate file?
