* tree.h (SSA_NAME_VAR): Return NULL_TREE if an IDENTIFIER_NODE
is recorded as var.

or its SSA_NAME_VAR.
(SET_SSA_NAME_VAR_OR_IDENTIFIER): New setter.
* tree-ssanames.c (make_ssa_name_fn): Handle creating anonymous
SSA names by passing a type instead of a variable decl.
(release_ssa_name): Use SET_SSA_NAME_VAR_OR_IDENTIFIER.

dump SSA names without a name as <anon>.

going to expand a decl.
(gimple_expand_cfg): Assign all SSA names of a partition the
decl we created for its leader.

Assert we only ever coalesce variables we computed conflicts for.

of anonymous names.

expanded from IVOPTs by creating a raw REG here.

(dump_function_to_file): Dump anonymous SSA names alongside
with their types in the variable list.
