i386-protos.h (memory_address_length): Add new bool argument.
* config/i386/i386-protos.h (memory_address_length): Add new bool
argument. Update all uses.
* config/i386/i386.c (memory_address_length): If not LEA insn, then
add length of addr32 prefix based on mode of base or index register.
(ix86_attr_length_address_default) <TYPE_LEA>: Do not handle SImode
addresses here. Update call to memory_address_length.
(ix86_print_address_operand): Use SImode_address_operand predicate.
* config/i386/predicates.md (SImode_address_operand): New.
* config/i386/i386.md (lea<mode>): Use SImode_address_operand
to calculate "mode" attribute. Use SImode_address_operand predicate
instead of open-coding accepted RTX codes.
