Test gcc.target/arm/mmx-2.c tests ARM iWMMXt functionality but fails to
compile if the compiler under test does not support that by default.
This patch adds -mcpu=iwmmxt. Now instead of failing to compile due to
unrecognized builtins, it fails with the ICE described in PR54338.
Tested on arm-none-eabi for multiple flags, checked in on trunk.
