Make CodeLocation inlineHEADmaster

CodeLocation constructor allocates d-ptr. This leads
to an extra allocation e.g. in JSSourceValue::location
which is called from convertToPropertyType for every
property evaluation.

While this is a micro-optmisation, it costs nothing
and allows to save several cycles.
