Description
After merging #935, <complex> will need the following intrinsics mentioned by @statementreply:
x86/x64:
_mm_fmsub_sd,_mm_set_sd,_mm_store_sd
arm64:,vfma_f64vld1_f64,vst1_f64,vneg_f64
Currently they're declared by <arm64/arm64_neon.h>, <i386/immintrin.h>, and <intrin.h>. We should consider copying the intrinsics in the first 2 headers, and moving the intrinsics in <intrin.h>, to <intrin0.h>, so that the STL can build faster.
Marking this as blocked until vcruntime is open-sourced.

Research direction
This work is blocked until vcruntime is open-sourced. Once unblocked, inspect <intrin0.h>, <arm64/arm64_neon.h>, <i386/immintrin.h>, and <intrin.h>; move or copy the listed x86/x64 and arm64 intrinsics so can build while reducing STL build overhead.
