builtins: avoid duplicating unwind declarations

Use unwind.h to get the declarations for unwinding interfaces. This header is
already provided by clang and gcc, so this adds no additional dependencies for
building the builtins library. It avoids the duplication which may drift over
time though.

Summary:
On Linux in some situations we can get SIGBUS instead of SIGSEGV on
stack overflow, so asan should handle SIGBUS as well as SIGSEGV.

Summary:
Introduce a single place where we specify flag type, name, default

Revert "Revert r224736: "[Sanitizer] Make CommonFlags immutable after initialization.""
...
Fix test failures by introducing CommonFlags::CopyFrom() to make sure
compiler doesn't insert memcpy() calls into runtime code.
Original commit message:
Protect CommonFlags singleton by adding const qualifier to
common_flags() accessor. The only ways to modify the flags are
SetCommonFlagsDefaults(), ParseCommonFlagsFromString() and
OverrideCommonFlags() functions, which are only supposed to be
called during initialization.

We've got some internal users that either aren't compatible with this or

soon. Sorry for the noise and any inconvenience.
