build!: optimize build process for Haswell CPUs

[lklimek]

Issue being fixed or feature implemented

In v1.6.2, we reverted change introducing CPU performance optimizations for x86-64 architecture.
We want these optimizations to be enabled in final release image.

We will still keep unoptimized code in debug images (the ones with -debug suffix) as a fallback mechanism.

What was done?

Enabled CPU optimizations for release images in:

• Rust
• C and C++ (CFLAGS, CXXFLAGS)

How Has This Been Tested?

Inspected using https://github.com/pkgw/elfx86exts/

Debug:
42 10.22 Instruction set extensions used: ADX, AES, AVX, AVX2, AVX512, BMI, BMI2, CMOV, MODE64, NOVLX, PCLMUL, SHA, SSE1, SSE2, SSE3, SSE41, SSSE3, VLX

Release:
42 4.391 Instruction set extensions used: ADX, AES, AVX, AVX2, AVX512, BMI, BMI2, CMOV, MODE64, NOVLX, PCLMUL, SHA, SSE1, SSE2, SSE41, SSE42, SSSE3, VLX

Breaking Changes

Dash Platform nodes must have Haswell instruction set, including: 64-bit extensions, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, POPCNT, CX16, SAHF, FXSR, AVX, XSAVE, PCLMUL, FSGSBASE, RDRND, F16C, AVX2, BMI, BMI2, LZCNT, FMA, MOVBE and HLE.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
