Remove global inline options.

The purpose of removing global inline options is to give
compiler the opportunity to do inline optimizations and inline
tunings for Android native codes.

By removing these global inline options now, the size of
almost all native libraries are reduced. And there is no
noticable performance degradation on webkit, gcstone and
skia benchmarks.
