Attempting to build libvpx ran into this issue with the download as of 
8/14/2014. Resolved by changing 

#if defined(_MSC_VER) && (_MSC_FULL_VER >= 160040219)

to

#if defined(_MSC_VER) && (_MSC_FULL_VER > 160040219)

VS 2010 sp1 immintrin does NOT define _xgetbv!

It works for me with vs2010sp1.  Investigating.
First thing I notice is the header ifdef's dont match the code ifdef.

This will only pull in the header needed for 64 bit:
#if !defined(__pnacl__) && !defined(__CLR_VER) && \
    !defined(__native_client__) && defined(_M_X64) && \
    defined(_MSC_VER) && (_MSC_FULL_VER >= 160040219)
#include <immintrin.h>  // For _xgetbv()
#endif

so this will do 32 bit
setlocal
set GYP_DEFINES=target_arch=ia32
set DEPOT_TOOLS_WIN_TOOLCHAIN=0
call python build\gyp_chromium -fninja -G msvs_version=2010 --depth=. 
libyuv_test.gyp
will not include the header.

r1046 includes the intrinsics header for xgetbv in 32 bit mode.
