	PR libstdc++/36104 part two
	* include/bits/hashtable.h: Revert to non-nested macro usage.
	* include/bits/hashtable_policy.h: Same.

	* ipa-split.c (find_return_bb): Use single_pred_p/single_pred_edge,
	simplify.

This greatly helps out the DImode division, and to a lesser
extent the DImode multiplication routines in libgcc2.c.

From-SVN: r169018

From-SVN: r169017

From-SVN: r169015

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

From-SVN: r169014

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

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

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

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

From-SVN: r169008

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

From-SVN: r169007

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

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

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.
