lavc/x86/hevc_add_res: Fix coeff overflow in ADD_RES_SSE_16_32_8
Fix overflow for coeff -32768 in function ADD_RES_SSE_16_32_8 with no
performance drop.(SSE2/AVX/AVX2)
./checkasm --test=hevc_add_res --bench
Mainline:
- hevc_add_res.add_residual [OK]
hevc_add_res_32x32_8_sse2: 127.5
hevc_add_res_32x32_8_avx: 127.0
hevc_add_res_32x32_8_avx2: 86.5
Add overflow test case:
- hevc_add_res.add_residual [FAILED]
After:
- hevc_add_res.add_residual [OK]
hevc_add_res_32x32_8_sse2: 126.8
hevc_add_res_32x32_8_avx: 128.3
hevc_add_res_32x32_8_avx2: 86.8
