Keith Randall fcf445dce2 runtime: initialize itab.hash always 
We weren't initializing this field for dynamically-generated itabs.
Turns out it doesn't matter, as any time we use this field we also
generate a static itab for the interface type / concrete type pair.
But we should initialize it anyway, just to be safe.

Performance on the benchmarks in CL 44339:
benchmark               old ns/op     new ns/op     delta
BenchmarkItabFew-12     1040585       26466         -97.46%
BenchmarkItabAll-12     228873499     4287696       -98.13%
