Internals refactor + renewed focus on perf (#17)
* 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)
