* params.def (PARAM_SALIAS_MAX_IMPLICIT_FIELDS): New
* params.h (SALIAS_MAX_IMPLICIT_FIELDS): New
* doc/invoke.texi: Documnet salias-max-implicit-fields.
* tree-ssa-alias.c (struct used_part): Add implicit_uses and
explicit_uses members.
(get_or_create_used_part_for): Initialize new fields.
(fieldoff_compare): New function.
(create_overlap_variables_for): Count number of fields, use
heuristic to determine whether to create subvars for vars with
only implicit uses.
Sort the field list by offset and avoid creating duplicate SFT's.
