x86-64: Simplify minimum ISA check ifdef conditional with if
Replace minimum ISA check ifdef conditional with if. Since MINIMUM_X86_ISA_LEVEL and AVX_X86_ISA_LEVEL are compile time constants, compiler will perform constant folding optimization, getting same results. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
