iOS simulator has the option to build with xcode instead of clang.
GN use_xcode_clang=true enables the xcode build.
As of version Xcode 9.2, the clang version used does not support
AVX512. The version reported is version 9, but for normal clang,
version 7 is sufficient to AVX512.
When a version of XCode does support AVX512, the version check can
be updated to allow AVX512 for newer versions of XCode.
with XCode 9.2 the following macro is set.

Scalar multiply expects a 'd' register. The "w" (float) uses 's' for float
and wont work with the multiply in 32 bit (it does in 64 bit).
A vector 2 of float passes as 'd' register.
A vector 4 of float passes as 'q' register.
This change copies the float into the first entry of a vector 2
and passes that. The optimizer removes the extra copy, allowing
the single float to use referenced as
