Introduce rtl_data::init_stack_alignment
Move this part of "expand"'s initialization of crtl into its own
method so that it can used by the RTL frontend when postprocessing
RTL dumps.
gcc/ChangeLog:
* cfgexpand.c (pass_expand::execute): Move stack initializations
to rtl_data::init_stack_alignment and call it.
* emit-rtl.c (rtl_data::init_stack_alignment): New method.
* emit-rtl.h (rtl_data::init_stack_alignment): New method.
