[PATCH] D87974: [Builtin] Add __builtin_zero_non_value_bits.

[Zoe Carver via Phabricator via cfe-commits]

@jwakely It looks like `UnsizedTail` causes a crash.

Other than that all the tests in this PR pass. It also looks like there's (at least) some support for unions and bitfields. This patch doesn't support those but I'm planning to add support as a follow-up.
