CPUID is part of x86_64 ISA to query CPU features. In order to determine AVX512F ISA extension, EAX and ECX needs to be set to 7 and 0 respectively before invoking `cpuid` instruction. This commit also removes inline assembly for __cpuid in favor of using compiler provided intrinsic functions. Both GCC and clang provides __cpuid like function via __cpuid_count intrinsic. This commit also creates a portable wrapper over compiler intrinsic functions, __cpuid and __cpuidex. `cpuid' provides base level ISA query and `cpuidex` provides extra extension information like AVX512F. These wrappers lean towards MSVC like API.
