The Hydrogen representation for binops was never changed to care about the
language mode. We thought this was ok, but it turns out we need to keep track
of it to make sure inlining doesn't mess with the "strongness" of binops.
Also added more rigorous inlining testing.

Implements the strong mode proposal's restrictions on implicit conversions
for the binary + operator. Test suite is also cleaned up/refactored to allow
easier testing of the comparison operators in the future.

Implements the strong mode proposal's restrictions on
implicit conversions for binary arithmetic operations, not
including the + special case. Adds some infrastructure
for future implementation of the restrictions for other
operators.
