re PR target/90568 (stack protector should use cmp or sub, not xor, to allow macro-fusion on x86)

PR target/90568
* config/i386/x86-tune-sched.c (ix86_macro_funsion_pair_p): Call
gen_attr_type just once instead of 4-7 times.  Formatting fixes.
Handle stack_protect_test_<mode> codegen similarly to corresponding
sub instruction.
