(expand_builtin_apply_args): If STACK_REGS is defined, generate USE
insns before the function body, thus showing which registers are
filled with parameters.
Reverse order of saving registers, more compact code for i387.
(expand_builtin_apply): Likewise.
(FP_mode_reg): Trimmed to a smaller size, less overhead.
(FP_MODE_REG): New macro over which FP_mode_reg will be accessed.
(mark_regs_pat, straighten_stack): New functions.
(reg_to_stack): Amend initialisation of FP_mode_reg.
Mark FP registers mentioned in USE insns before NOTE_INSN_FUNCTION_BEG.
(get_true_reg): Eliminate FP subreg accesses in favour of the actual FP
register in use.
(record_reg_life_pat): Make it work on SUBREGs as well. Make use of the new
mark_regs_pat function. Handle USE insns if called unnested.
(record_reg_life): Don't check for QImode again, we know that it is there.
Process CALL_INSNs like all other insns, they might `use' some FP argument
registers if register passing.
(stack_result_p): Changed in stack_result and returning an rtx.
(stack_reg_life_analysis): Take a new stackentry state argument.
Use stack_result and the rtx to mark using mark_regs_pat. This ensures that
types that need multiple FP registers are handled correctly
Delete the no_live_regs shortcut to save space.
Use stackentry state to determine filled registers.
(replace_reg): Accept COMPLEX_FLOAT as well.
(move_for_stack_reg): Optimise away some pointer dereferencing.
(subst_stack_regs): Make sure the stack is in the right order and of the right
size for register passing.
(goto_block_pat): Make sure the stack is in the right order to return possible
multi-register values from the function.
(convert_regs): Fix comment about CALL_INSN, it's no longer valid.
Make sure the stack is of the right size and in the right order to return
possible multi-register values from the function.

(fold, case RROTATE_EXPR): Sometimes commute logical op with rotate.
Delete pair of counteracting shifts.
