[PATCH 2/2] remove val_ssa_equiv_hash_traits

[tbsaunde+gcc at tbsaunde dot org]

From: Trevor Saunders <tbsaunde+gcc@tbsaunde.org>

Hi,

this is pretty trivial cleanup after the previous patch, but could wait for
next stage 1 if people don't like the very small risk.

boostrappped + regtested on x86_64-linux-gnu, ok?
