Hi,

This patch enables shrink-wrapping by default for ARM.
I have tested shrink-wrapping and no correctness problems came out or runtime regressions.
Although the gain may be small, the code looks nicer with shrink-wrapping enabled and the performance could just be better.

For the record shrink-wrapping was introduced after this review:
http://reviews.llvm.org/D9210

OK to commit?

Thanks,
-Quentin
