This is a chery-pick if you consider reducing the context to -C2
a cherry-pick; WordIsSmi has been renamed to TaggedIsSmi upstream.
Original commit message:
[builtins] Fix pointer comparison in ToString builtin.
This fixes the bogus {Word32Equal} comparison in the ToString
builtin implementing Object.prototype.toString to be a pointer-size
{WordEqual} comparison instead. Comparing just the lower half-word
is insufficient on 64-bit architectures.
