Yawning Angel f9b9521bf0 core/crypto/_fiat/field_curve25519: Use multiply to calculate the mask
Largely for consistency with the generic code, either is valid with Odin
semantics, but this is easier to comprehend.

Yawning Angel d72db2698b core/crypto/_fiat: Hedge against LLVM cleverness
Recent LLVM is getting smart to the point where the optimizer can change
a traditional constant-time conditional swap into a pointer swap.

Ensure that this does not happen by force-disabling optimization.
Additionally, disable inlining the relevant routines such that manual
inspection in optimized builds is still reasonably easy to do.

This package implements the X25519 key agreement scheme as specified in
RFC 7748, using routines taken from fiat-crypto and Monocypher.
