cmd/ld: drop gcargs, gclocals symbols from symbol table

Update issue 6853

Every function now has a gcargs and gclocals symbol
holding associated garbage collection information.
Put them all in the same meta-symbol as the go.func data
and then drop individual entries from symbol table.

Removing gcargs and gclocals reduces the size of a
typical binary by 10%.

This CL appears to have broken the linux-arm-cheney-panda builder.
