      [Arm]: Enable use of extended out-of-line constant pool for Arm. · 40af47d4
      rmcilroy@chromium.org authored 
       - Adds support to the Arm assembler to use extended constant pools.
 - Update (set_)target_address_at to support extended constant pool load
   updates.
 - Replace Operand::is_single_instruction with Operand::instructions_required
   Due to the fact that different constant pool load types require different
   numbers of instructions.
 - Various cleanups of ConstantPoolBuilder to cleaner integration of the
   extended constant pool building.
 - Update GetRelocatedValue such that offsets to both map_check and bool_load
   are explicitly provided, rather than location of bool_load being inferred
   based on map_check, since the code inbetween is no longer of a predictable
   size.
 - Update MacroAssembler::GetRelocatedValueLocation() to add support for
   getting a value from an extended constant pool entry.
 - Update Debug::SetAfterBreakTarget() to use target_address_from_return_address
   when checking for debug breaks at constant pool load points.
 - Change ConstantPoolIterateBody to iterate over both heap and code pointer in
   the small section before moving onto the extended section, to work around the
   requirement of the serializer that pointers are iterated in-order.
 - Increase old_pointer_space SizeOfFirstPage() to offset the fact that constant
   pools are now in the old pointer space (rather than code).

      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.
