Remove :PENTIUM from *FEATURES*

code/misc.lisp:: * Don't register :PENTIUM feature.

code/time.lisp:: * Replace :pentium with :x86; we assume all x86's have the rdtsc instruction.

compiler/x86/float.lisp:: compiler/x86/system.lisp:: * Remove the vop guard on :pentium; assume we're always running on a pentium or better.
