ipa: do not make localaliases for target_clones [PR101261]

Browse Source 
PR ipa/101261

gcc/ChangeLog:

	* symtab.c (symtab_node::noninterposable_alias): Do not create
	  local aliases for target_clone functions as the clonning pass
	  rejects aliases.

gcc/testsuite/ChangeLog:

	* gcc.target/i386/pr101261.c: New test.
