[PATCH] Fix misuse of always_inline attribute in 3 hotpatch tests

[Jakub Jelinek]

Hi!

always_inline attribute is meaningful only for functions declared
inline, and the compiler even warns about this, so it is unclear
to me why the tests are attempting to use that.

	* gcc.target/s390/hotpatch-compile-15.c: Remove dg-prune-output
	directives.
	(hp3, hp4): Add inline keyword.
	* gcc.target/s390/hotpatch-19.c: Remove dg-prune-output directive.
	(hp2): Add inline keyword.
	* gcc.target/s390/hotpatch-19.c: Remove dg-prune-output directives.
	(hp2): Add inline keyword.
