[PATCH] Swap ealias and esra pass ordering

[Richard Biener]

As said in the other mail esra corrupts ealias info by eventually
adding new PHI nodes but at the same time doesn't benefit from
points-to info.  Also esra may improve PTA precision by exposing
more SSA names.

Bootstrapped on x86_64-unknown-linux-gnu, testing in progres.

Queued for stage1.

Richard.
