Summary:
1. Update ubsan_interface.inc to make the test happy.
2. Switch interface_symbols_linux and interface_symbols_darwin to C++ to import __ubsan_handle_dynamic_type_cache_miss
3. Switch interface_symbols_windows to C++ for consistency.

Summary:
`pvalloc` appears to not be available on Android. Mark the failing test as
unsupported on that platform.

Summary:
Last one of the `pvalloc` overflow checks!
`CheckForPvallocOverflow` was introduced with D35818 to detect when `pvalloc`
would wrap when rounding up to the next multiple of the page size.
Add this check to ASan's `pvalloc` implementation.

atos is the default symbolizer on Apple's compiler for quite a few years now.
llvm-symbolizer is quite fragile on Darwin: for example, unless a .dSYM
file was explicitly generated symbolication would not work.
It is also very convenient when the behavior of LLVM open source
compiler matches to that of Apple's compiler on Apple's platform.
Furthermore, llvm-symbolizer is not installed on Apple's platform by
default, which leads to strange behavior during debugging: the test
might fail under lit (where it has llvm-symbolizer) but would run
properly when launched on the command line (where it does not, and atos
would be used).
Indeed, there's a downside: atos does not work properly with inlined
functions, hence the test change.
We do not think that this is a major problem, as users would often
compile with -O0 when debugging, and in any case it is preferable to
symbolizer not being able to symbolize.

Summary:
Set proper errno code on alloction failures and change some
implementations to satisfy their man-specified requirements:
LSan: valloc and memalign
ASan: pvalloc, memalign and posix_memalign
Changing both allocators in one patch since LSan depends on ASan allocator in some configurations.

This fixes an issue with the emission of lifetime markers for struct-returning Obj-C msgSend calls. When the result of a struct-returning call is ignored, the temporary storage is only marked with lifetime markers in one of the two branches of the nil-receiver-check. The check is, however, not required when the result is unused. If we still need to emit the check (due to consumer arguments), let's not emit the memset to zero out the result if it's unused. This fixes a use-after-scope false positive with AddressSanitizer.

Summary:
Operator new interceptors behavior is now controlled by their nothrow
property as well as by allocator_may_return_null flag value:
- allocator_may_return_null=* + new() - die on allocation error
- allocator_may_return_null=0 + new(nothrow) - die on allocation error
- allocator_may_return_null=1 + new(nothrow) - return null
Ideally new() should throw std::bad_alloc exception, but that is not
trivial to achieve, hence TODO.
