    [arm] Clean up use of IsSupported and IsEnabled. · 73518a90
    jacob.bramley authored
    CpuFeatures::IsSupported(feature) indicates that the feature is
    available on the target. AssemblerBase::IsEnabled(feature) indicates
    that we've checked for support (using CpuFeatureScope). The main benefit
    is that we can test on (for example) ARMv8, but have some assurance that
    we won't generate ARMv8 instructions on ARMv7 targets.
    
    This patch simply cleans up the usage, which had become inconsistent.
    The instruction emission functions now check not only that their
    dependent features are supported, but also that we've verified that
    using CpuFeatureScope.
