📄 Description

As discussed in #2819 the usage of AVX2 ops could improve performance quite significantly in a lot of cases which is why this PR sets -march=x86-64-v3 as the target CPU architecture. This strikes a good balance between enabling performance-critical instructions (e.g., AVX2) and maintaining compatibility with relatively older systems.

The x86-64-v3 target corresponds to Intel's Haswell era architectures. Haswell was introduced in 2014. The vast majority of users today have CPUs that are significantly newer. Systems with pre-Haswell CPUs are unlikely to meet the performance requirements for PS4 emulation, making support for them impractical.

As -march=x86-64-v3 also implies -mtune=x86-64-v3, the mtune part was removed.
