Hans Wennborg 2f2c04c157 Drop TARGET_IPHONE_SIMULATOR macro check 
Recent versions of Clang always define these TARGET_ macros (to 0 or 1
as appropriate) for Apple targets.
https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5249072
made the code correctly check the *value* of the macro rather than
whether it was defined or not.

However, the code was still broken when actually targeting the iOS
simulator (where the macro is now 1).

It seems the use of this macro was just incorrect, and the code only
worked since it was never defined at all.

The original use of the macro in this file was added in
2c8108e6c2
but it 's not quite clear to me why.

All other uses have subsequently been removed, e.g. in
6a1d01220a

this removes the last instance, and should fix the iOS simulator builds.

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 on Arm.
  • Optimized for MSA on Mips.
  • Optimized for RVV on RISC-V.
