rmcilroy@chromium.org 7f429e62c3 [Arm]: Simplify compile-time Arm feature detection. 
Simplify the compile time feature detection on Arm:
 - Define CAN_USE_XXX definitions unconditionally for all target/host
   toolchain combinations
 - Rename arm_test / ARM_TEST to arm_test_noprob / ARM_TEST_NO_FEATURE_PROBE
 - Don't set ARM_TEST_NO_FEATURE_PROBE implicitly on the simulator to make
   make simulator / native more consistent
 - Unify CpuFeatures::PrintTarget for simulator and native builds
 - Remove unecessary CAN_USE_VFP_INSTRUCTIONS definition for android (this is
   the default for arm_fpu=default)
 - Add a CpuFeatures::Probe() before calling CpuFeatures::PrintFeatures() in PrintHelp
    to ensure we have probed features before printing them.
