Optimize 32-bit ARGBRotate (0, 90, 180, 270) across Intel x86/x64
architectures (SSE2, AVX2, AVX512BW), with matching kernels for ARM
(NEON, SVE2, SME), WASM, LoongArch (LSX, LASX), and RISC-V (RVV):
- Replace column-by-column ScaleARGBRowDownEven gather loops in
ARGBTranspose (90/270) with full-plane horizontal tile transposes:
- AVX512BW (TransposeWxH_32_AVX512BW / TransposeNx4_32_AVX512BW):
Transpose 16x16 blocks across zmm0..zmm31 using 4-stage
vpunpckldq/hdq, vpunpcklqdq/hqdq, and vshufi32x4 butterflies with
k-masked right and bottom tails, eliminating Any wrappers and scalar
C edge fallbacks.
- AVX2 (TransposeWxH_32_AVX2 / TransposeNx4_32_AVX2):
Transpose 8x8 blocks across ymm0..ymm15 using vpunpck* and
vperm2i128 with vpmaskmovd masked tails.
- SSE2 (Transpose4x4_32_SSE2 / Transpose4x4_32_Any_SSE2):
Transpose 4x4 blocks in xmm registers.
- Implement ARGBRotate180 directly via ARGBMirror with negative height,
avoiding intermediate row buffer allocations and extra copies.
- Implement ARGBRotate0 via ARGBCopy.
Speedup vs Before (1275x1650, US Letter 150 DPI, 1000 iterations):
CPU | 0 deg | 90 deg | 180 deg | 270 deg
---------------------|---------|---------|---------|--------
Intel Ice Lake | 1.02x | 1.34x | 1.18x | 1.33x
Intel Skylake-X | 1.02x | 1.20x | 1.07x | 1.13x
Intel Emerald Rapids | 1.01x | 1.07x | 1.00x | 1.07x
Intel AVX-512 vs C | 1.00x | 2.67x | 2.41x | 2.63x
