Bug 1449798 - Remove GenericSpecifiedValues::ShouldComputeStyleStruct and mSIDs. r=emilio

Browse Source 
This was useful because nsRuleData in the old style system may not hold
all the data, but the only subclass ServoSpecifiedValues is always able
to hold any data, and thus passes NS_STYLE_INHERIT_MASK to mSIDS. Given
this, this method and mSIDs seems to be useless and can be removed.
