For other ABIs, -msingle-pic-base makes gcc omit loading of the PIC
register in function prologues. This patch makes the option affect
ELFv2 too.

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.
* src/powerpc/ffi_sysv.c (ffi_prep_cif_sysv_core): Count fprs,
gprs, and stack words separately.

Limit the MEMSET (setmemsi pattern) and MEMCPY (movmemsi pattern)
instructions to 0-511 bytes. There is a hardware limitation on large
MEMSET, MEMCPY operations that the library versions of memset() and
memcpy() deal with.

When determining the type of an index for a string/array indexing
expression, the gofrontend would disallow floating-point and complex
values even if they were integral and throw an internal error. This
patch changes gofrontend to use an integral type context when
determining the types of a string/array index.

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.)
Patch passed bootstrap and check on x86_64-linux with ISL-0.15.
