Log:
* doc/md.texi (madd@var{m}@var{n}4): Extend to fixed-point modes.
(ssmadd@var{m}@var{n}4, usmadd@var{m}@var{n}4): Document.
* optabs.c (init_optabs): Initialize ssmadd_widen_optab and
usmadd_widen_optab.
* optabs.h (OTI_ssmadd_widen, OTI_usmadd_widen): New optab_indexes.
(ssmadd_widen_optab, usmadd_widen_optab): Define.
* genopinit.c (optabs): Fill in ssmadd_widen_optab and
usmadd_widen_optab.
* tree.h (NON_SAT_FIXED_POINT_TYPE_P, SAT_FIXED_POINT_TYPE_P,
FIXED_POINT_TYPE_P): Define.
* expr.c (expand_expr_real_1): Support saturating and non-saturating
multiply and add for fixed-point types.
* c-typeck.c (c_common_type): Initialize mclass to 0 to avoid warnings.
* tree-ssa-reassoc.c (break_up_subtract_bb): We can do reassociation
for non-saturating fixed-point types
(reassociate_bb): Likewise.
