H.J. Lu	7c124e3714	x86: Install <bits/platform/x86.h> [BZ #27958] ... 1. Install <bits/platform/x86.h> for <sys/platform/x86.h> which includes <bits/platform/x86.h>. 2. Rename HAS_CPU_FEATURE to CPU_FEATURE_PRESENT which checks if the processor has the feature. 3. Rename CPU_FEATURE_USABLE to CPU_FEATURE_ACTIVE which checks if the feature is active. There may be other preconditions, like sufficient stack space or further setup for AMX, which must be satisfied before the feature can be used. This fixes BZ #27958.
