When we're running tests under ASAN or MSAN, they're compiled with -O1, which
enables tail call elimination. This causes backtrace_test to fail: the compiler
performs tail call elimination for call3_nothrow, but it can't for call3_throw,
leading to a mismatched frame count. Disable tail call elimination (and
inlining, just to be explicit) to avoid this.

Currently there is only support for a -fno-exceptions libc++ build. This is
problematic for functions such as std::terminate() which are defined in
libc++abi and using any of those functions throws away most of the benefits
of using -fno-exceptions (code-size). This patch introduces a -fno-exceptions
libc++abi build to address this issue.
This new variant of libc++abi cannot be linked against any with-exceptions
code as some symbols necessary for handling exceptions are missing in this
library.
