As a safety precaution, ANGLE writes the commit hash, optimization level,
and adapter ID to its binary format. However, this hurts portability
between systems by making shader pre-compilation/caching artificially
system-specific.
The shader compiler doesn't take the target adapter into account, and the
optimization level information discarded by ANGLE anyway. So, allow ANGLE
to bypass these checks on systems where precompilation is required (i.e.
WinRT). The default mechanism still applies unless
ANGLE_ENABLE_UNIVERSAL_BINARY is passed as a define.
