Eliminate redundant signatures.

Eliminate redundant signatures.

The check to see that a method signature was redundant was not
handling generics correctly.  This CL fixes it, so that we no
longer emit redundant signatures for methods on generic
classes.  This should help with startup and code size a bit.

Note that this is dependent on this CL
https://codereview.chromium.org/2642763006/ .  I didn't bother to change the
base patch set since the first two files of this CL (only) are changes from the
previous CL and can be ignored for this review, but let me know if you'd rather
I change the base patch set to eliminate them.

LGTM! Nice to see the SDK JS get smaller.
