H.J. Lu 6914be53bd 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
