[patch, ia64, committed] Fix vector instructions on IA64 HP-UX

[Steve Ellcey]

Richard,

I went back to the IA64 vectorization patch you sent me earlier and
tried to get it working on HP-UX.  I believe I have it working now and
would like to check in the modified patch.  I have attached the full
patch to this email.  The differences between this and your patch are
listed below.

The vec_interleave_* change is the biggest difference.  When I
tried to switch between unpack.l and unpack.h instructions based on
TARGET_BIG_ENDIAN I get lots of failures.  Even when I try to compensate
in the vect.md and ia64.c code where we make gen_vec_interleave_* calls
I continue to get failures.

I am still working on the vec_extract_evenv2sf, vec_extract_oddv2sf code
to try and get that working.

I wanted to see if you had any comments before I check it in.

Changes between this patch and your original patch:

vec_interleave_low*/_high* - I swap arguments but do not swap .h for .l.

reduc_splus_v2sf  - Added 'if (TARGET_BIG_ENDIAN)' to swap call.
reduc_smax_v2sf
reduc_smin_v2sf

vec_extract_evenv2si - Added 'if (TARGET_BIG_ENDIAN)' to inverleave
call.
vec_extract_oddv2si  - Ditto.

vec_extract_evenv2sf - Temporarily turned off to avoid regressions.
vec_extract_oddv2sf  - Ditto.
