Frank Barchard eee4597984 Fix _M_X86 to _M_IX86 
Fix _M_X86 to _M_IX86 for Visual C 32 bit

Visual C defines _M_IX86 for 32 bit x86, not _M_X86.
row.h and row_win.cc tested _M_X86, so a real 32 bit Visual C build
got neither USE_ROW_WIN nor USE_ROW_GCC, row_win.cc compiled to nothing,
and the HAS_*_AVX2 defines for all x86 platforms were skipped.
clang-cl and Android x86 are unaffected since clang defines __i386__.

Testing:
ninja -C out/Release libyuv_unittest && out/Release/libyuv_unittest
ninja -C out/Release_x86 libyuv_unittest && out/Release_x86/libyuv_unittest
ninja -C out/rowwin libyuv_unittest && out/rowwin/libyuv_unittest
blaze test --config=windows_x86 //third_party/libyuv:libyuv_test
blaze build --config=android_x86 //third_party/libyuv:libyuv

README.md

libyuv is an open source project that includes YUV scaling and conversion functionality.

  • Scale YUV to prepare content for compression, with point, bilinear or box filter.
  • Convert to YUV from webcam formats for compression.
  • Convert to RGB formats for rendering/effects.
  • Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
  • Optimized for SSSE3/AVX2 on x86/x64.
  • Optimized for Neon/SVE2/SME on Arm.
  • Optimized for MSA on Mips.
  • Optimized for RVV on RISC-V.
