the vtable symbol may be undefined because the class is missing its key function (see https://lld.llvm.org/missingkeyfunction)

LLVM_ENABLE_LTO=Thin results in different, but similar errors

Figure out a sane way to handle missing execinfo.h for MSAN

Need to figure out a sane way to handle missing execinfo.h

Probably best way is to handle this with CMake to allow external libexecinfo?
What can we use to detect if we need to additional link?

CMake should also probably search for execinfo.h and disable MSAN build
if it is not found.

Disabling a sanitizer results in a build failures

A lot of these pile up if a sanitizer is disabled. Using make can get past this,
but ninja refuses to continue.

<support/musl/xlocale.h> doesn't always get included?

Taking <support/musl/xlocale.h> out of #ifdefs (copypasting it after the next #endif), everything compiles fine. Which doesn't make sense, since putting a #warning inside the ifdef branch where the include is still shows.
