Pack MCSymbol::HasName in to a spare bit in the section/fragment union.

This is part of an effort to pack the average MCSymbol down to 24 bytes.

The HasName bit was pushing the size of the bitfield over to another word,
so this change uses a PointerIntPair to fit in it to unused bits of a
PointerUnion.
