John Stiles 8397365524 Optimize away same-value ternaries. 
A ternary of the form `anything ? value : value` can be reduced to a
comma-expression of the form `anything, value`. This seems like a rare
case in real code, but it's easy enough to detect with our existing
toolbox.

The `anything` test-expression will be eliminated from the expression
if it has no side effects, using our existing constant-folding rules
for the comma expression.
