TargetLoweringInfo may report that an integer should be promoted, but it maybe provide a size that isn't natively supported by the target register file... So check this before trying to perform a promotion.

This is to fix some  chromium issues: https://bugs.chromium.org/p/chromium/issues/detail?id=1031978, https://bugs.chromium.org/p/chromium/issues/detail?id=1031979
