Arnold Schwaighofer 5b80649dec IRGen: Use LLVM -Os mode to compile swift ...

We don't want LLVM aggresively inlining llvm.memcpy instructions and similar
aggressive optimizations to save code size.

For example the X86 target sets max stores per memset to 16 and max stores per
memcpy to 8 (vs 4).

Loop optimizations are also a lot more aggressive.
