mn10300: Emit retf instruction

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.

From-SVN: r169013

mn10300: tidy pic address loading

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.

From-SVN: r169012

mn10300: Cleanup all arithmetic.

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.

From-SVN: r169010

mn10300: Explicitly represent MDR in multiply and divide.

Note that the mulsidi3_internal pattern is structured so
as to let the lower-subregs pass fully split the result.

From-SVN: r169008

mn10300: Expose the MDR register to register allocation.

Note that nothing uses the "z" constraint yet except the one
move pattern; this merely defines the register class properly.

From-SVN: r169007

mn10300: Cleanup legitimate addresses

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.

From-SVN: r169006

mn10300: Cleanup secondary reloads

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.

From-SVN: r169005

mn10300: Re-write move patterns.

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.
