[PATCH] i386/x86-64: Generalize X86_FEATURE_CONSTANT_TSC flag

Define it for i386 too.

This is a synthetic flag that signifies that the CPU's TSC runs
at a constant P state invariant frequency.

Fix up the logic on x86-64/i386 to set it on all known CPUs.
Use the AMD defined bit to set it on future AMD CPUs.
