This commit goes through the `runtests` folder of the `filetests` test suite and ensure that everything which uses simd or float-related instructions on x64 is executed with the baseline support for x86_64 in addition to adding in AVX support. Most of the instructions used have AVX equivalents so this should help test all of the equivalents in addition to the codegen filetests in the x64 folder.
