Hi,

This patch will modify the target-support.exp to enable vect_int,
vect_shift, vect_no_int_max, and vect_no_align for loongson target. So
that the auto-vectorization tests will be done.

Here's the test result when apply the early patch
(http://gcc.gnu.org/ml/gcc-patches/2010-07/msg00357.html) on trunk:

		=== gcc Summary ===

# of expected passes		55
# of unexpected failures	1
# of expected failures		6
# of unsupported tests		488
/home/xmj/tools/build-trunk/gcc/xgcc  version 4.6.0 20100706
(experimental) (GCC)

Here's the test result when apply this patch too:

		=== gcc Summary ===

# of expected passes		1020
# of unexpected failures	9
# of unexpected successes	15
# of expected failures		91
# of unsupported tests		141
/home/xmj/tools/build-trunk/gcc/xgcc  version 4.6.0 20100706
(experimental) (GCC)

The tests are run using cross compiler plus ssh, compile on ia64, run
on loongson2f.

ChangeLog

* target-supports.exp: enable vect_int, vect_shift, vect_no_int_max,
and vect_no_align for loongson target.

Thanks,
Eric
