gas: Extend .symver directive
Extend .symver directive to update visibility of the original symbol and
assign one original symbol to different versioned symbols:
.symver foo, foo@VERS_1, local # Change foo to a local symbol.
.symver foo, foo@VERS_2, hidden # Change foo to a hidden symbol.
.symver foo, foo@@VERS_3, remove # Remove foo from symbol table.
.symver foo, bar@V1 # Assign foo to bar@V1 and baz@V2.
.symver foo, baz@V2
