From 50fa993d67f8a20322c27c1a77e7efcf826531fc Mon Sep 17 00:00:00 2001
From: Alex Light <allight@google.com>

Subject: Svelter libart-compiler

Added new environment variable ART_{TARGET,HOST}_CODEGEN_ARCHS which
may be set to 'all', 'svelte' or a space separated list of architectures.

When compiled with ART_{TARGET,HOST}_CODEGEN_ARCHS='all' (the default
value) dex2oat will be able to generate output for all supported
architectures.

When compiled with ART_TARGET_CODEGEN_ARCHS='svelte'
only the architectures of the TARGET will be included. When
ART_HOST_CODEGEN_ARCHS='svelte' all architectures the target includes
and the host architectures will be included on the host dex2oat.

If a list of architectures is given only those will be included.
