GR_VIRTUAL_PREFERRED_STACK_BOUNDARY.

(virtual_preferred_stack_boundary_rtx,
VIRTUAL_PREFERRED_STACK_BOUNDARY_REGNUM): Define.
(LAST_VIRTUAL_REGISTER): Increase by one.
(REGNO_PTR_FRAME_P): Use LAST_VIRTUAL_POINTER_REGISTER
instead of LAST_VIRTUAL_REGISTER.

virtual_preferred_stack_boundary_rtx.
* emit-rtl.c (init_virtual_regs): Handle
VIRTUAL_PREFERRED_STACK_BOUNDARY_REGNUM.
(init_emit_regs): Initialize virtual_preferred_stack_boundary_rtx.
* explow.c (round_push): If crtl->preferred_stack_boundary
is smaller than MAX_SUPPORTED_STACK_ALIGNMENT, use
virtual_preferred_stack_boundary_rtx alignment instead of
crtl->preferred_stack_boundary alignment.
(allocate_dynamic_stack_space): Use CONST_INT_P and REG_P
macros. Never decrease crtl->preferred_stack_boundary,
use crtl->preferred_stack_boundary or MAX_SUPPORTED_STACK_ALIGNMENT
instead of PREFERRED_STACK_BOUNDARY. Don't modify
stack_pointer_delta in dynamic allocation, even when size
is constant.
(probe_stack_range, anti_adjust_stack_and_probe): Use CONST_INT_P
macro.

Should be fixed now on the trunk, on 4.4 and 4.5 I've so far reverted the old
