Hi!

One missing spot where clobber stmts need to be ignored.
Testcase needs profile feedback and is quite large, so not
adding it to testsuite; bootstrapped/regtested on x86_64-linux
and i686-linux, approved by richi in the PR, committed to trunk.

	PR tree-optimization/52376
	* ipa-split.c (split_function): Ignore CLOBBER stmts.
