[dev.link] cmd/compile, cmd/asm: add length to hashed symbols
While working on deduplicating pcdata, I found that the following hashed
symbols would result in the same:
[] == [0,0,0,0....]
This makes using content addressable symbols untenable for pcdata.
Adding the length to the hash keeps the dream alive.
No difference in binary size (darwin, cmd/compile), spurious
improvements in DWARF phase memory.
