Rework assembly to be compatible with LTO (#231)
* rework assembler register/mem and constraint declarations

* Introduce constraint UnmutatedPointerToWriteMem

* Create invidual memory cell operands

* [Assembly] fully support indirect memory addressing

* fix calling convention for exported procs

* Prepare for switch to intel syntax to avoid clang constant propagation asm symbol name interfering OR pointer+offset addressing

* use modifiers to prevent bad string mixin fo assembler to linker of propagated consts

* Assembly: switch to intel syntax

* with working memory operand - now works with LTO on both GCC and clang and constant folding

* use memory operand in more places

* remove some inline now that we have lto

* cleanup compiler config and benches

* tracer shouldn't force dependencies when unused

* fix cc on linux

* nimble fixes

* update README [skip CI]

* update MacOS CI with Homebrew Clang

* oops nimble bindings disappeared

* more nimble fixes

* fix sha256 exported symbol

* improve constraints on modular addition

* Add extra constraint to force reloading of pointer in reg inputs

* Fix LLVM gold linker running out of registers

* workaround MinGW64 GCC 12.2 bad codegen in t_pairing_cyclotomic_subgroup with LTO

Sha256 refactor (#206)
* sha256: separate message scheduling and state updates to help implement specific use-cases like #205; also implement SSSE3 acceleration (2006, Intel Core 2 Duo)

* sha256: simplify update flow, store less metadata in context

* sha256: Fix reworked update function

* Implement x86 hardware SHA acceleration

* typo

Productionize: move protocols top-level vs backend (#179)

Hash to curve - BLS12-381 (#110)
* Hash to Curve: impl expand_message_xmd

* Try to precompute part of hash to curve at compile-time

* sha256 bench - use the new hashes module

* [WIP] smoke test hash to field

* Implement hash_to_field with expected output

* unoptimized hash-to-curve G2 for BLS12-381

* Don't run sanitizer on hash to field as it uses GC-ed strings

Fix test suite (#116)
* Pin nim-serialization. Workaround #113 and https://github.com/status-im/nim-serialization/issues/33

* Need to workaround nimble installing dependency multiple times

* non-interactive

* UB sanitizer missing on mingw

* Fix OpenSSL benchmark on non-Linux platforms

* Accelerate CI:
- Skip 32-bit on 64-bit tests
- Only test leaf functionality.

* Don't define -fstack-protector-all with MinGW

* skip line functions and cyclotomic tests (already tested in pairing) + only compile the benches don't run them.
