* Lay out the refactoring objectives and tradeoffs
* Refactor the 32 and 64-bit primitives [skip ci]
* BigInts and Modular BigInts compile
* Make the bigints test compile
* Fix modular reduction
* Fix reduction tests vs GMP
* Implement montegomery mul, pow, inverse, WIP finite field compilation
* Make FiniteField compile
* Fix exponentiation compilation
* Fix Montgomery magic constant computation for 2^64 words
* Fix typo in non-optimized CIOS - passing finite fields IO tests
* Add limbs comparisons [skip ci]
* Fix on precomputation of the Montgomery magic constant
* Passing all tests including 𝔽p2
* modular addition, the test for mersenne prime was wrong
* update benches
* Fix "nimble test" + typo on out-of-place field addition
* bigint division, normalization is needed: https://travis-ci.com/github/mratsim/constantine/jobs/298359743
* missing conversion in subborrow non-x86 fallback - https://travis-ci.com/github/mratsim/constantine/jobs/298359744
* Fix little-endian serialization
* Constantine32 flag to run 32-bit constantine on 64-bit machines
* IO Field test, ensure that BaseType is used instead of uint64 when the prime can field in uint32
* Implement proper addcarry and subborrow fallback for the compile-time VM
* Fix export issue when the logical wordbitwidth == physical wordbitwidth - passes all tests (32-bit and 64-bit)
* Fix uint128 on ARM
* Fix C++ conditional copy and ARM addcarry/subborrow
* Add investigation for SIGFPE in Travis
* Fix debug display for unsafeDiv2n1n
* multiplexer typo
* moveMem bug in glibc of Ubuntu 16.04?
* Was probably missing an early clobbered register annotation on conditional mov
* Note on Montgomery-friendly moduli
* Strongly suspect a GCC before GCC 7 codegen bug (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87139)
* hex conversion was (for debugging) not taking requested order into account + inlining comment
* Use 32-bit limbs on ARM64, uint128 builtin __udivti4 bug?
* Revert "Use 32-bit limbs on ARM64, uint128 builtin __udivti4 bug?"
This reverts commit 087f9aa7fb40bbd058d05cbd8eec7fc082911f49.
* Fix subborrow fallback for non-x86 (need to maks the borrow)
* add Travis config for x86_64 and ARM64
* Add Travis badge
* add stew test dependency
* comment out unused 64-bit word extended precision arithmetic for ARM CI
