cpu_id fails to compile with 32-bit mingw-w64

[GoogleCodeExporter]

What steps will reproduce the problem?
1. use i686-w64-mingw32-g++ to compile cpu_id.cc

$ i686-w64-mingw32-g++ -I include source/cpu_id.cc -c -o /dev/null
source/cpu_id.cc: In function ‘int libyuv::TestOsSaveYmm()’:
source/cpu_id.cc:101:9: error: expected ‘(’ before ‘{’ token
source/cpu_id.cc:102:5: error: expected primary-expression before ‘xor’ 
token
source/cpu_id.cc:102:16: error: ‘ecx’ was not declared in this scope
source/cpu_id.cc:103:5: error: expected ‘;’ before ‘_asm’

What is the expected output? What do you see instead?
Compiles successfully. Build failure.

What version of the product are you using? On what operating system?
r1046

Please provide any additional information below.
mingw's windows.h defines _M_IX86, but it doesn't support VS-style inline 
assembly. Potential fix attached.

Confirmed.  This works:
c:\mingw64\bin\x86_64-w64-mingw32-c++.exe -I include source/cpu_id.cc -c -o 
cpu_id.o
but this fails
c:\mingw64\bin\x86_64-w64-mingw32-c++.exe -m32 -I include source/cpu_id.cc -c 
-o cpu_id.o
