-ansi-alias is enabled by default at -O2 and above on Linux*

This change was introduced in Intel® C++ Compiler 15.0 for Linux.

To align more closely with gcc, -ansi-alias is enabled by default at –O2 and above.  gcc enables -fstrict-aliasing, the alternate option of -ansi-alias, at -O2, -O3 and -Os.
