Specifically:
- Start using %expect_crash.
- Provide an implementation of __ubsan::getDynamicTypeInfoFromVtable
for the Microsoft C++ ABI. This is all that is needed for CFI
diagnostics; UBSan's -fsanitize=vptr also requires an implementation of
__ubsan::checkDynamicType.
- Build the sanitizer runtimes against the release version of the C
runtime, even in debug builds.
- Accommodate demangling differences in tests.

This reverts commit r221445. This change leads to false positives
reports from -fsanitize=vptr. See original commit thread for more
details.

When the __virtual_mask is set, __offset_flags >> __offset_shift yields
an offset into the vtable. Dereferencing this vtable slot gets us the
vbase offset.
Adjust a test case to verify that this, in fact, works.

shrink the binary size of the ubsan runtime.
Also fix a bug where long-running processes could eventually trigger a crash in
the runtime by filling up the cache. I've not found a nice way to add a test for
this crasher; ideas welcome.

comparing type_info names, since the latter have better uniqueness guarantees
in practice.

pointing at the bad location and a snippet of nearby memory values. This is
strictly best-effort; reading these bytes to display the note could lead to a
seg fault, and that's explicitly OK.

bogus gcc warning. Take this opportunity to move the declaration to the header,
since it's part of the API of this file.
