[Bug target/18580] New: Vectorizer failures

["ebotcazou at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

This PR is aimed at tracking the vectorizer failures on the SPARC.  As of today,
we have 11 failures on SPARC 32-bit:

FAIL: gcc.dg/vect/vect-13.c scan-tree-dump-times vectorized 1 loops 1
FAIL: gcc.dg/vect/vect-27.c scan-tree-dump-times vectorized 1 loops 1
FAIL: gcc.dg/vect/vect-27a.c scan-tree-dump-times vectorized 1 loops 1
FAIL: gcc.dg/vect/vect-29.c scan-tree-dump-times vectorized 1 loops 1
FAIL: gcc.dg/vect/vect-29a.c scan-tree-dump-times vectorized 1 loops 1
FAIL: gcc.dg/vect/vect-48a.c scan-tree-dump-times vectorized 1 loops 1
FAIL: gcc.dg/vect/vect-56a.c scan-tree-dump-times vectorized 1 loops 1
FAIL: gcc.dg/vect/vect-72.c scan-tree-dump-times vectorized 1 loops 1
FAIL: gcc.dg/vect/vect-72a.c scan-tree-dump-times vectorized 1 loops 1
FAIL: gcc.dg/vect/vect-77.c scan-tree-dump-times vectorized 1 loops 1
FAIL: gcc.dg/vect/vect-77a.c scan-tree-dump-times vectorized 1 loops 1

which are either related to max vector operations (vect-13.c) or unaligned
operations (the remaining 10 failures).
