Subject: [testsuite] : Require non_strict_align effective target for

Hello!

These two tests require non_strict_aligned effective target, since IPA
fails in tree_non_mode_aligned_mem_p () for "cow" and "calf"
candidates for STRICT_ALIGNMENT targets. Mode alignment requires 32
bytes, while data is aligned to 8 bytes.

	* gcc.dg/ipa/ipa-sra-2.c: Add dg-require-effective-target
	non_strict_align.
	* gcc.dg/ipa/ipa-sra-6.c: Ditto.

Tested on x86_64-pc-linux-gnu and alphaev68-pc-linux-gnu, where the
patch "fixes":

FAIL: gcc.dg/ipa/ipa-sra-2.c scan-tree-dump eipa_sra "About to replace
expr cow_.*D.->red with \\*ISRA"
FAIL: gcc.dg/ipa/ipa-sra-2.c scan-tree-dump eipa_sra "About to replace
expr cow_.*D.->green with ISRA"
FAIL: gcc.dg/ipa/ipa-sra-2.c scan-tree-dump eipa_sra "About to replace
expr calf_.*D.->red with \\*ISRA"
FAIL: gcc.dg/ipa/ipa-sra-2.c scan-tree-dump eipa_sra "About to replace
expr calf_.*D.->green with ISRA"
FAIL: gcc.dg/ipa/ipa-sra-6.c scan-tree-dump-times eipa_sra "foo " 1

OK for mainline and 4.6 branch?

Uros.
