Stop reload1.c warning from breaking bootstrap

Some host-target combinations get bogus warnings about orig_dup
being used uninitialized.  I tried to coerce the current uninit
pass to handle this case, but the patch I ended up with only worked
by accident because of the strange way in which the pass handles
limit cases.  (If we have more than MAX_NUM_CHAINS chains, it silently
drops the excess chains and continues regardless, so it's quite easy
to come up with cases where the predicates for either the definition
or the use consider an arbitrary subset of the actual conditions.)

For now this patch turns -Wmaybe-uninitialized into a warning for
the affacted function.  It will be a warning even if someone turns
off warnings on the command line, but I don't think that's important.

Bootstrapped and regression-tested on x86_64-linux-gnu.  Also tested
with a cross-compiler to sparc-linux-gnu (which also triggered the
warning for me).

* reload1.c (elimination_costs_in_insn): Locally turn
-Wmaybe-uninitialized into a warning.

Warn when comparing nonnull arguments to NULL in a function.

If an argument is marked as nonnull then passing in a NULL argument

Fix PowerPC ICE due to secondary_reload ignoring reload replacements

The reason for this PR is that insns emitted by secondary reload
patterns are being generated without taking into account other reloads
that may have occurred.  We run into this problem when an insn has a
pseudo that doesn't get a hard reg, and the pseudo is used in a way
that requires a secondary reload.  In this case the secondary reload
is needed due to gcc generating a 64-bit gpr load from memory insn
with an address offset not a multiple of 4.

Remove limit_scops

This patch removes graphite-scop-detection.c:limit_scops function and fix
related issues arising because of that. The functionality limit_scop was added
as an intermediate step to discard the loops which graphite could not
handle. Removing limit_scop required handling of different cases of loops and
surrounding code.  The scop is now larger so most test cases required 'number of
scops detected' to be fixed. By increasing the size of scop we can now optimize
loops which are 'siblings' of each other. This could enable loop fusion on a
number of loops. Since in the graphite framework we mostly want to opimize
loop-nests/adjacent-loops, we now discard scops with less than 2 loops. We
also discard scops without any data references.

Essentially:
 - Remove limite_scops.
 - Only select scops when there are at least two loops (loop nest or, side by side).
 - Discard loops without data-refs.
 - Fix test cases.

Passes bootstrap and reg-test.
