* Proof-of-Concept Assembly code generator * Tag inline per procedure so we can easily track the tradeoff on tower fields * Implement Assembly for modular addition (but very curious off-by-one) * Fix off-by one for moduli with non msb set * Stash (super fast) alternative but still off by carry * Fix GCC optimizing ASM away * Save 1 register to allow compiling for BLS12-381 (in the GMP test) * The compiler cannot find enough registers if the ASM file is not compiled with -O3 * Add modsub * Add field negation * Implement no-carry Assembly optimized field multiplication * Expose UseX86ASM to the EC benchmark * omit frame pointer to save registers instead of hardcoding -O3. Also ensure early clobber constraints for Clang * Prepare for assembly fallback * Implement fallback for CPU that don't support ADX and BMI2 * Add CPU runtime detection * Update README closes #66 * Remove commented out code
