Hi, 
V2 update to incorporate suggested changes.

Move the vsx related content from the altivec-7-be test into
a new vsx-7-be test.  Split out the VSX specific bits into a vsx-7.h
header file, and include that when appropriate.

(v2 updates).   Adjust target stanza to allow 32bit targets to run test.
Updated scan-assembler stanzas to accommodate codegen variations involving
lxvd2x in BE versus LE versus P9.    Sniff tested across p6-p9 systems
with -m32,-m64.  Test currently runs clean.

This fixes up results as seen on some power systems.

	* gcc.target/powerpc/altivec-7-be.c:  Remove VSX content, allow
	-32 bit target.
	* gcc.target/powerpc/altivec-7.h: Remove VSX content.
	* gcc.target/powerpc/vsx-7-be.c: New test (VSX content).
	* gcc.target/powerpc/vsx-7.h: New include (VSX content).
	* gcc.target/powerpc/altivec-7-le.c: Add vsx-7.h include.

Only one space after ":".  "32-bit target".

These three conditions are overlapping, and don't cover everything?

The first and the third are both enabled when running on a BE p9 system
(not that those exist, but still).

None are active if compiling for LE p9 on another LE system.

Should the first line have  {powerpc*le-*-* && p9vector_ok}  instead?


Okay for trunk with that sorted out.  Thanks!
