obj_int_extract for Visual Studio 

Enable extraction of assembly offsets from compiled examples in MSVS.
This will allow us to remove some stub functions from x86 assembly since
we will be able to reliably determine structure offsets at compile time.

see ARM code for examples:
vp8/encoder/arm/armv5te/
vpx_scale/arm/neon/
