testsuite: Use attribute "noipa" in sibcall tests

...instead of attribute "noinline".

For cris-elf, testsuite/gcc.dg/sibcall-3.c and sibcall-4.c "XPASS",
without sibcalls being implemented.  On inspection, recurser_void2 is
set to be an assembly-level alias for recurser_void1 as in
".set _recurser_void2,_recurser_void1" for both these cases.

IOW, those "__attribute__((noinline))" should be
"__attribute__((noipa))".  The astute reader will notice that I also
adjust test-cases where self-recursion should occur: as mentioned in
sibcall-1.c "self-recursion tail calls are optimized for all targets,
regardless of presence of sibcall patterns".  But, that optimization
happens even with "noipa", as observed by the test-cases still passing
for cris-elf after patching.  Being of a small mind, I like
consistency, but not all the time, so there's hope.

testsuite:
	* gcc.dg/sibcall-1.c, gcc.dg/sibcall-10.c,
	gcc.dg/sibcall-2.c, gcc.dg/sibcall-3.c,
	gcc.dg/sibcall-4.c, gcc.dg/sibcall-9.c: Replace
	attribute "noinline" with "noipa".
