All unoptimized tests should now pass when Swift is built with
'build-script -- --swift-stdlib-enable-resilience=1'.
There are still some issues when the tests themselves are built
with optimizations via 'check-swift-validation-optimize'.
Fixes <rdar://problem/28409189>.
This API should have been converted to use the
new Builtin before it was introduced here:

Add UnsafeRawPointer type and API. (#3677)
But it looks like that was dropped during during some local merge. It's not
likely to be a problem until developers start adopting the new API and the
optimizer starts using TBAA aggressively. The other "raw" API's are binding
memory or using memmove, so those are safe.
