[RS6000] Don't be too clever with dg-do run and dg-do compile

Otherwise some versions of dejagnu go ahead and run the vsx tests
below when they should not.  To best cope with older dejagnu, put
"run" before "compile", the idea being that if the second dg-do always
wins then that won't cause fails.

The altivec tests also need -save-temps for the scan-assembler test to
occur when vms_hw.

	* gcc.target/powerpc/vsx-load-element-extend-char.c: Put "dg-do run"
	before "dg-do compile", and make them mutually exclusive.
	* gcc.target/powerpc/vsx-load-element-extend-int.c: Likewise.
	* gcc.target/powerpc/vsx-load-element-extend-longlong.c: Likewise.
	* gcc.target/powerpc/vsx-load-element-extend-short.c: Likewise.
	* gcc.target/powerpc/vsx-store-element-truncate-char.c: Likewise.
	* gcc.target/powerpc/vsx-store-element-truncate-int.c: Likewise.
	* gcc.target/powerpc/vsx-store-element-truncate-longlong.c: Likewise.
	* gcc.target/powerpc/vsx-store-element-truncate-short.c: Likewise.
	* gcc.target/powerpc/altivec-consts.c: Likewise, add -save-temps.
	* gcc.target/powerpc/le-altivec-consts.c: Likewise.
