tests/tcg: build sha1-vector with O3 and compare 

The aim of this is to test code generation for vectorised operations.
Unfortunately gcc struggles to do much with the messy sha1 code (try
-fopt-info-vec-missed to see why). However it's better than nothing.

We assume the non-vectorised output is gold and baring compiler bugs
the outputs should match.
