arch/x86: x86_64 implies SSE2 support
Enable SSE2 (and SSE) when compiling for x86_64. Compilers often assume
SSE2 is present and enabled when targeting x86_64.
This fixes:
- lzma decompression code is compiled with the -Ofast flag
- 'everything' when compiling with clang.
This mostly affects qemu targets, which did not have this flag selected
yet.
TESTED on qemu.
