Security
* Updates to constant time C code so that compilers are less likely to use
conditional instructions (Clang was observed to use these). Conditional
instructions might have an observable difference in timing. Introduce
assembly implementations for 32 and 64-bit Arm which are guaranteed not
to use conditional instructions.
