d30c05c850ead352dad5ea0dc32942feb2942986 by Abseil Team <absl-team@google.com>:

Place STL exception functions underneath the ABSL_HAVE_EXCEPTIONS #ifdef.

The STL exception functions are not present in the Android NDK, so Abseil fails to build as part of ANGLE in AOSP.   This CL places the various STL exception throwing functions inside #ifdef ABSL_HAVE_EXCEPTIONS blocks so they are removed during Android builds since neither ANGLE nor the NDK support exceptions by default.
