+ * Updates to constant-time C code so that compilers are less likely to use
+ conditional instructions, which can have an observable difference in
+ timing. (Clang has been seen to do this.) Also introduce assembly
+ implementations for 32- and 64-bit Arm and for x86 and x86-64, which are
+ guaranteed not to use conditional instructions.
