[PATCH] rs6000: Guard __builtin_{un,}pack_vector_int128 with vsx [PR109932]

[Kewen.Lin]

Hi,

As PR109932 shows, builtins __builtin_{un,}pack_vector_int128
should be guarded under vsx rather than power7, as their
corresponding bif patterns have the conditions TARGET_VSX
and VECTOR_MEM_ALTIVEC_OR_VSX_P (V1TImode).  This patch is to
move __builtin_{un,}pack_vector_int128 to stanza vsx to ensure
their supports.

Bootstrapped and regtested on powerpc64-linux-gnu P7/P8/P9 and
powerpc64le-linux-gnu P9 and P10.

I'll push this next week if no objections.

BR,
Kewen

[PATCH, committed] testsuite: Check int128 effective target for pr109932-{1,2}.c [PR110230]

[Kewen.Lin]

Hi,

This patch is to make newly added test cases pr109932-{1,2}.c
check int128 effective target to avoid unsupported type error
on 32-bit.  I did hit this failure during testing and fixed
it, but made a stupid mistake not updating the local formatted
patch which was actually out of date.

Pushed as obvious in r14-1776-g16eb9d69079d76.

BR,
Kewen
