powerpc: fix ifunc-sel.h fix asm constraints and clobber list
As pointer out on the mailing list, the inline assembly code in sysdeps/powerpc/ifunc-sel.h doesn't have a list of clobbered registers and used wrong constraints. This patch fixes that. I verified it doesn't introduce any change in the generated code. Changelog: * sysdeps/powerpc/ifunc-sel.h (ifunc_sel): Add "11", "12", "cr0" to the clobber list. Use "i" constraint instead of "X". (ifunc_one): Add "12" to the clobber list. Use "i" constraint instead of "X".
