* config/i386/i386.c (X86_64_VARARGS_SIZE): Removed.
(setup_incoming_varargs_64): Set/check ix86_varargs_gpr_size and
ix86_varargs_fpr_size. Use ix86_varargs_gpr_size instead of
REGPARM_MAX. Don't set ix86_save_varrargs_registers.
(ix86_va_start): Check ix86_varargs_gpr_size and
ix86_varargs_fpr_size instead of cfun->va_list_gpr_size and
cfun->va_list_fpr_size, respectively. Subtract 8*REGPARM_MAX
from frame pointer if ix86_varargs_gpr_size == 0.
(ix86_compute_frame_layout): Updated.
* config/i386/i386.h (ix86_save_varrargs_registers): Removed.
(ix86_varargs_gpr_size): Define.
(ix86_varargs_fpr_size): Likewise.
(machine_function): Remove save_varrargs_registers.
Add varargs_gpr_size and varargs_fpr_size.
* gcc.target/i386/amd64-abi-3.c: New test.
