rs6000: Add "cannot_copy" attribute, use it (PR67788, PR67789)
After the shrink-wrapping patches the prologue will often be pushed
"deeper" into the function, which in turn means the software trace cache
pass will more often want to duplicate the basic block containing the
prologue. This caused failures for 32-bit SVR4 with -msecure-plt PIC.
This configuration uses the load_toc_v4_PIC_1 instruction, which creates
assembler labels without using the normal machinery for that. If now
the compiler decides to duplicate the insn, it will emit the same label
twice. Boom.
It isn't so easy to fix this to use labels the compiler knows about (let
alone test that properly). Instead, this patch wires up a "cannot_copy"
attribute to be used by TARGET_CANNOT_COPY_P, and sets that attribute on
these insns we do not want copied.

call scev analysis in scop-detection as in sese-to-poly
Before our rewrite of the scop detection, we used to not have a valid SESE
region under hand, and so we used to do more ad-hoc analysis of data references
by trying to prove that at all levels of a loop nest the data references would
be still valid.
Now that we have a valid SESE region, we can call the scev analysis in the same
way on the same computed loop nest in the scop-detection as in the sese-to-poly.
Next step will be to cache the data references analyzed in the scop detection
and not compute the same info in sese-to-poly.
The patch fixes block-1.f90 that used to ICE on x86_64-linux when compiled with
-m32. Patch passed bootstrap with BOOT_CFLAGS="-g -O2 -fgraphite-identity

[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.)
