More noinline marks

[Jan Hubicka]

Hi,
more of noinline markers.  These are mostly for i386 alignment hack on runtimes
not honoring 64bit stack alignment.  I think we don't need these anymore,
because we do dynamic stack alignment correctly now, but the problem is just
fact that when extra function gets inlined, it confuses pattern matching the
testcases.  I also had to disable early inlining for ipa-4.c as the function
expected to be cloned by ipa-cp are too small otherwise.

Regtested x86_64-linux, will commit it shortly.

	* gcc.target/i386/align-main-1.c (check): Mark noinline.
	* gcc.target/i386/align-main-2.c (check): Mark noinline.
	* gcc.dg/ipa/ipa-4.c: Disable early inlining.
	* gcc.dg/vect/vect-iv-10.c (main1): Mark noinline.
	* gcc.dg/vect/costmodel/i386/costmodel-vect-33.c (main1): Mark noinline.
	* gcc.dg/vect/costmodel/x86_64/costmodel-vect-33.c (main1): Mark noinline.
	* gcc.dg/vect/pr31699.c (foo): Mark noinline.
	* gcc.dg/vect/pr18400.c (main1): Mark noinline.
