Than McIntosh 6636b3f2fc [dev.link] cmd/link/internal/loader: support 'variant' relocations
Add support to the loader for getting/setting the 'variant' property
of a symbol relocation. The variant property handles unusual or
infrequently used relocations that have both a type and a variant of
that type (this is needed for S390).

In the sym.Symbol world, a relocation variant is a field on the
'relocExt' extension that is part of sym.Reloc. In this new
implementation for the loader, reloc variants are stored in a side
table (a map) in the loader, and accessed via loader methods.
