commit 3118f473950b4b707d78622053fc4934a2d3f13a
Author: Ross McIlroy <rmcilroy@chromium.org>

[TurboFan] Fix type checks for lowering SpeculativeNumberBinop.

Ensure we only lower SpeculativeNumberBinops to a pure operator for
non-string plain primitives. Previously we could lower if a value might be
the-hole, however this would fail a CHECK in ConvertInputsToNumber which
expects a plain primitive.
