[RS6000] Correct powerpc sysv stack argument accounting
ppc32 starts using the stack for integer arg passing when we run out
of integer arg passing registers. Similarly, we start using the stack
for floating point args when we run out of floating point registers.
The decision on where an integer arg goes does not depend on number of
floating point args, nor does the decision on where a floating point
arg goes depend on number of integer args. Alignment of stack args
also simply depends on number of stack args.
This patch untangles the horrible mess we had, with intarg_count being
wrongly used to count both integer args and stack words.

remove dead code of commutative_reductions
This code is not used anymore after we removed the previous loop optimizer (not
based on the ISL scheduler.) We will add back the detection of commutative
reductions after we improve the code generation of scalar dependences (by not
going out of SSA for scalar dependences just to expose them to the data
dependence graph.)

Redesign Graphite scop detection
Redesign Graphite scop detection for faster compiler time and detecting more SCoPs.
Existing algorithm for SCoP detection in graphite was based on dominator tree
where a tree (CFG) traversal was required for analyzing an SESE. The tree
traversal is linear in the number of basic blocks and SCoP detection is
(probably) linear in number of instructions. That algorithm utilized a generic
infrastructure of SESE which does not directly represent loops. With regards to
graphite framework, we are only interested in subtrees with loops. The new
algorithm is geared towards tree traversal on loop structure. The algorithm is
linear in number of loops which is faster than the previous algorithm.
Briefly, we start the traversal at a loop-nest and analyze it recursively for
validity. Once a valid loop is found we find a valid adjacent loop. If an
adjacent loop is found and is valid, we merge both loop nests otherwise we form
a SCoP from the previous loop nest, and resume the algorithm from the adjacent
loop nest. The data structure to represent an SESE is an ordered pair of edges
(entry, exit). The new algoritm can extend a SCoP in both the directions. With
this approach, the number of instructions to be analyzed for validity reduces to
a minimal set. We start by analyzing those statements which are inside a loop,
because validity of those statements is necessary for the validity of loop. The
statements outside the loop nest can be just excluded from the SESE if they are
not valid.
This patch depends on: https://gcc.gnu.org/ml/gcc-patches/2015-09/msg02024.html
Passes (c,c++,fortran) regtest and bootstrap.

revert to assign_parms assignments using default defs
Revert the fragile and complicated changes to assign_parms designed to
enable it to use RTL assigments chosen by cfgexpand, and instead have
cfgexpand use the RTL assignments by assign_parms, keying them off of
the default defs that are now necessarily introduced for each parm and
result. The possible lack of a default def was already a problem, and
the fallbacks in place were not enough, as shown by PR67312. We now
have checking asserts in set_rtl that verify that we're assigning to
each var a piece of RTL that matches the expectations set forth by
use_register_for_decl.

* cfgexpand.c (parm_in_stack_slot_p): Remove.
(ssa_default_def_partition): Remove.
(get_rtl_for_parm_ssa_default_def): Remove.
(set_rtl): Check that RTL assignments match expectations.
Loop on SUBREGs, CONCATs and PARALLELs subexprs. Set only the
default def location for params and results. Record SSA names
or types in REG and MEM attrs, respectively.
(set_parm_rtl): New.

unassigned addresses.
(adjust_one_expanded_partition_var): Don't accept NULL RTL on
deferred stack alloc vars.
(expand_used_vars): Skip partitions holding parm default defs.
Move adjust_one_expanded_partition_var loop...
(pass_expand::execute): ... here. Drop redundant assert.
Adjust comments before the final loop over all ssa names.
Require assigned rtl of parms and results to match exactly.
Reset its attributes to match them, not any other variables in
the same partition.
(expand_debug_expr): Use entry value for PARM's default defs
only iff they have zero nondebug uses.

(assign_parm_setup_block): Revert. Use set_parm_rtl instead
of SET_DECL_RTL. Set up a REG if the parm demands so.
(assign_parm_setup_reg): Revert. Consolidated SET_DECL_RTL
calls into a single set_parm_rtl. Set up a temporary RTL
temporarily for expand_assignment.
(assign_parm_setup_stack): Revert. Use set_parm_rtl.
(assign_parms_unsplit_complex): Revert. Use set_parm_rtl.
(assign_bounds): Revert.
(assign_parms): Revert. Use set_parm_rtl.
(allocate_struct_function): Relayout result and parms of
non-abstruct functions.
(expand_function_start): Revert. Use set_parm_rtl. If the
