C2: multiple slices for flattened value type arrays

[Roland Westrelin]

Hi Tobias,

> - Wrong indentations. For example, type.cpp:3071
> - Excess/missing whitespace around parentheses. For example:

>   - assert( offset() >= 0, "" ) -> assert(offset() >= 0, "")
>   - _bits(bits){} -> _bits(bits) { }
> - Pointer asterisk position. For example:
>   - static const TypePtr *make(..) -> static const TypePtr* make(..)

Thanks for looking at this. I will do a quick pass of clean up and push
it.

Roland.
