"Experimental" features in releases

[David Edelsohn]

	-ftree-loop-linear enables a number of features and
transformations.  Which part, exactly, is experimental?  You are quoting
from the documentation for the option, but Dan may be referring to a
particular transformation.  I thought the failure and algorithm
correctness was related to creating perfect loop nests used by other
transformations, not all of the tree loop linear.

	I think this discussion is losing a lot in the summary.
