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

Field sqrt optimization (#168)
* add more Fp tests for Twisted Edwards curves

* add fused sqrt+division bench

* Significant fused sqrt+division improvement for any prime field over algorithm described in  "High-Speed High-Security Signature", Bernstein et al, p15 "Fast decompression", https://ed25519.cr.yp.to/ed25519-20110705.pdf

* Activate secp256k1 field benches + spring renaming of field multiplication

* addition chains for inversion and sqrt of Curve25519

* Make isSquare use addition chains

* add double-prec mul/square bench for <256-bit prime fields.

Double-Precision towering (#155)
* consistent naming for dbl-width

* Isolate double-width Fp2 mul

* Implement double-width complex multiplication

* Lay out Fp4 double-width mul

* Off by p in square Fp4 as well :/

* less copies and stack space in addition chains

* Address https://github.com/mratsim/constantine/issues/154 partly

* Fix #154, faster Fp4 square: less non-residue, no Mul, only square (bit more ops total)

* Fix typo

* better assembly scheduling for add/sub

* Double-width -> Double-precision

* Unred -> Unr

* double-precision modular addition

* Replace canUseNoCarryMontyMul and canUseNoCarryMontySquare by getSpareBits

* Complete the double-precision implementation

* Use double-precision path for Fp4 squaring and mul

* remove mixin annotations

* Lazy reduction in Fp4 prod

* Fix assembly for sum2xMod

* Assembly for double-precision negation

* reduce white spaces in pairing benchmarks

* ADX implies BMI2
