Via expander, pre- and post-reload patterns. The pre-reload
pattern is defined to allow lower_subregs totally split the
DImode values.

Now that we properly track the life of MDR, we can emit
the RETF instruction if MDR has not been modified. This
insn is 3-4 cycles faster since the return address is
already loaded.

There's little reason to greatly complicate things by splitting
the pic_load patterns and using complex rtl to make it work out.
Instead, use the %= marker to generate unique numbers and emit
the entire load_pic sequence at once.
At the same time, collect all references to outgoing_args_size
into mn10300_frame_size, and all computations of register save
area size into mn10300_initial_offset.

For addition and logicals, define an operation-plus-flags update pattern
in preparation for compare elimination. In addition, clean up the way
we compare and validate CC_MODEs. Define NEG in terms of NOT; this is
smaller and allows a non-clobbering destination alternative.

Allow REG+REG and POST_MODIFY addressing for AM33. Fix AM33 base and
index register classes. Remove a bunch of register class combinations
that aren't really useful after this cleanup.

Handles output reloads for QI/HImode properly; previously we were
only handing input reloads properly.
Handles reloads involving the stack pointer better; note that the
AM33 allows copying SP to DATA_REGS as well as ADDRESS and EXTENDED.

Use the "D" and "A" constraints, and the enabled attribute to
unify all ofthe integer move patterns. Delete the fake double
word move patterns; let the middle-end generate subregs as required.
Unfortunately, this somehow exposes a register pressure problem
with the udivmod pattern. This is properly fixed with subsequent
patches that expose the MDR register.
In the meantime it is highly desirable to to preserve bisect-ability
of the patch series, so disable this pattern for AM30.
