Mangle inline class members

<IMPL_SUFFIX> for method is a method signature hash,
if method value parameter types contain inline class types,
otherwise 'impl'.

Constructor methods are named as 'constructor-<IMPL_SUFFIX>'.

Synthesized 'box' and 'unbox' methods are named as
'<METHOD_NAME>-<IMPL_SUFFIX>'.

Erased implementations of overriding and non-overriding methods
are named as '<METHOD_NAME>-<IMPL_SUFFIX>'.

Fully specialized implementation of 'equals' will have a special suffix.
