ANGLE's ASSERT macro was often not printing the error message before
crashing. The printing happens in the destructor of a temporary object,
but the temporary object is not guaranteed to be destroyed before ASSERT
calls __builtin_trap(). This change fixes it by introducing a new FATAL
log severity that moves the __builtin_trap() call into the destructor
after the message is printed.
