    Decouple CpuFeatures from serializer state. · fe243379
    yangguo@chromium.org authored
    Traditionally, we cross compile a snapshot iff the serializer is enabled.
    This will change in the future.
    
    Changes:
     - CpuFeatures probing is done once per process, depending on whether we
       cross compile.
     - CpuFeatures are consolidated into the platform-independent assembler.h
       as much as possible.
     - FLAG_enable_<feature> will only be checked at probing time (already the
       case for ARM).
     - The serializer state is cached by the MacroAssembler.
     - PlatformFeatureScope is no longer necessary.
     - CPUFeature enum values no longer map to CPUID bit fields.
