* tree-scalar-evolution.c (scev_const_prop):
* tree-phinodes.c (remove_phi_node): Add argument
RELEASE_LHS_P. If given, release the SSA name on the LHS of
the PHI node.
Update all users.
* tree-ssa-dce.c: Remove forward declarations for static
functions. Re-arrange functions bodies as needed.
(find_obviously_necessary_stmts): Never mark PHI nodes as
obviously necessary.
