Always use a reg as 4th arg of dmac/fmac even if ignored by insn.
Uses of `b' as a constraint in multi-word reload patterns should be `c'.

(define_attr type): New types for SQRT.
(call patterns): Use SCRATCH for LR0.
Use new predicate call_operand so that some integers can be
used as addresses; fix CALLI so it doesn't accept constant.
(EXBYTE, EXTHW, INBYTE, INHW): Use ZERO_EXTEND instead of AND
when combine will make it.
Use PSImode for BP value and don't reference BP explicitly.
Clean up define_expands for these operations.
(rotlsi3): Use PSImode pseudo for FC.
(sign_extend): Sign extension insns clobber BP.
({load,store}_multiple): Use PSImode pseudo for CR.
(MTSR): Add pattern for TRUNCATE from SImode to PSImode.
(sqrtsf2, sqrtdf2, movpsi): New patterns.
(load/store bytes/halfword): Clean up to accept temporaries as
input and use PSImode when required.
(movhi, movqi): Allocate temporaries here.
(reload_inqi, reload_outqi, reload_inhi, reload_outhi): New patterns.
(movdf, movdi, movti): Use SCRATCH for BP register.
(reload_{in,out}{df,di,ti}): New patterns.
