Jeremy Faller b249703e3c [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.
