crypto: x86/sha256 - Add parentheses around macros' single arguments
The macros FOUR_ROUNDS_AND_SCHED and DO_4ROUNDS rely on an
unexpected/undocumented behavior of the GNU assembler, which might
change in the future
(https://sourceware.org/bugzilla/show_bug.cgi?id=32073).
M (1) (2) // 1 arg !? Future: 2 args
M 1 + 2 // 1 arg !? Future: 3 args
M 1 2 // 2 args
Add parentheses around the single arguments to support future GNU
assembler and LLVM integrated assembler (when the IsOperator hack from
the following link is dropped).
