rs6000: Make the ctr* patterns allow ints in vector regs (PR71763)
Similar to PR70098, which is about integers in floating point registers,
we can have the completely analogous problem with vector registers as well
now that we allow integers in vector registers. So, this patch solves it
in the same way. This only works for targets with direct move.
To recap: register allocation can decide to put an integer mode value in
a floating point or vector register. If that register is used in a bd*z
instruction, which is a jump instruction, reload can not do an output
reload on it (it does not do output reloads on any jump insns), so the
float or vector register will remain, and we have to allow it here or
recog will ICE. Later on we will split this to valid instructions,
including a move from that fp/vec register to an int register; it is this
move that will still fail (PR70098) if we do not have direct move enabled.

[6/7] Explicitly classify vector loads and stores
This is the main patch in the series. It adds a new enum and routines
for classifying a vector load or store implementation.
Originally there were three motivations:
(1) Reduce cut-&-paste
(2) Make the chosen vectorisation strategy more obvious. At the
moment this is derived implicitly from various other bits of
state (GROUPED, STRIDED, SLP, etc.)
(3) Decouple the vectorisation strategy from those other bits of state,
so that there can be a choice of implementation for a given scalar
statement. The specific problem here is that we class:
for (...)
{
... = a[i * x];
... = a[i * x + 1];
}
as "strided and grouped" but:
for (...)
{
... = a[i * 7];
... = a[i * 7 + 1];
}
as "non-strided and grouped". Before the patch, "strided and
grouped" loads would always try to use separate scalar loads
while "non-strided and grouped" loads would always try to use
load-and-permute. But load-and-permute is never supported for
a group size of 7, so the effect was that the first loop was
vectorisable and the second wasn't. It seemed odd that not
knowing x (but accepting it could be 7) would allow more
optimisation opportunities than knowing x is 7.
Unfortunately, it looks like we underestimate the cost of separate
scalar accesses on at least aarch64, so I've disabled (3) for now;
see the "if" statement at the end of get_load_store_type. I think
the patch still does (1) and (2), so that's the justification for
it in its current form. It also means that (3) is now simply a
case of removing the FIXME code, once the cost model problems have
been sorted out. (I did wonder about adding a --param, but that
seems overkill. I hope to get back to this during GCC 7 stage 1.)

[1/7] Remove unnecessary peeling for gaps check
I recently relaxed the peeling-for-gaps conditions for LD3 but
kept them as-is for load-and-permute. I don't think the conditions
are needed for load-and-permute either though. No current load-and-
permute should load outside the group, so if there is no gap at the end,
the final vector element loaded will correspond to an element loaded
by the original scalar loop.
The patch for PR68559 (a missed optimisation PR) increased the peeled
cases from "exact_log2 (groupsize) == -1" to "vf % group_size == 0", so
before that fix, we didn't peel for gaps if there was no gap at the end
of the group and if the group size was a power of 2.
The only current non-power-of-2 load-and-permute size is 3, which
doesn't require loading more than 3 vectors.
The testcase is based on gcc.dg/vect/pr49038.c.
