Tweak a couple of testcases

gcc.c-torture/execute/ipa-sra-2.c doesn't pass on SPARC64/Solaris 10 because 
it returns a value read from uninitialized memory.  gcc.dg/pr41963.c doesn't 
pass on SPARC/Solaris 9 because of a missing declaration for fabsf.

Tested on SPARC/Solaris 9, SPARC64/Solaris 10 and x86/Linux, applied on the 
mainline as obvious.

	* gcc.c-torture/execute/ipa-sra-2.c: Use calloc instead of malloc.
	* gcc.dg/pr41963.c: Do not include math.h.  Declare fabsf manually.
