* function.h (struct rtl_data): Add max_dynamic_stack_alignment.
* cfgexpand.c (gimple_expand_cfg): Initialise it.
* explow.c (allocate_dynamic_stack_space): Set it. Simplify
alignment requirements given the known alignment of dynamic_offset.
* function.c (instantiate_virtual_regs): Align dtnamic_offset.
