[PATCH] D146426: [Sema] Fix crash on __fp16 parameters in template instantiations

[Ilya Biryukov via Phabricator via cfe-commits]

ilya-biryukov added a comment.

I landed the fix to unbreak our crashes and explored a bit of the alternative solution.

Digging a bit deeper, trying to always set non-null parameters causes ~30 test failures, but the ones I looked at so far look more localized and should be fixable.
Some started producing more diagnostics (I assume those are just noise, but  I haven't checked closely), it might be trickier to sort those out.

I'll try to spend some more time on it and come up with a better fix some time this week.
