  [X86][Clang] VectorExprEvaluator::VisitCallExpr / InterpretBuiltin - add SSE/AVX VPTEST/VTESTPD/VTESTPS intrinsics to be used in constexpr (#160428)

Fix #158653

Add handling for:
```
ptestz128 / ptestz256 → (a & b) == 0.
ptestc128 / ptestc256 → (~a & b) == 0
ptestnzc128 / ptestnzc256 → (a & b) != 0  AND  (~a & b) != 0.
vtestzps / vtestzps256 → (S(a) & S(b)) == 0.
vtestcps / vtestcps256 → (~S(a) & S(b)) == 0.
vtestnzcps / vtestnzcps256 → (S(a) & S(b)) != 0  AND  (~S(a) & S(b)) != 0.
vtestzpd / vtestzpd256 → (S(a) & S(b)) == 0.
vtestcpd / vtestcpd256 → (~S(a) & S(b)) == 0.
vtestnzcpd / vtestnzcpd256 → (S(a) & S(b)) != 0  AND  (~S(a) & S(b)) != 0.
```
Add corresponding test cases for:
```
int _mm_test_all_ones (__m128i a)
int _mm_test_all_zeros (__m128i mask, __m128i a)
int _mm_test_mix_ones_zeros (__m128i mask, __m128i a)
int _mm_testc_pd (__m128d a, __m128d b)
int _mm256_testc_pd (__m256d a, __m256d b)
int _mm_testc_ps (__m128 a, __m128 b)
int _mm256_testc_ps (__m256 a, __m256 b)
int _mm_testc_si128 (__m128i a, __m128i b)
int _mm256_testc_si256 (__m256i a, __m256i b)
int _mm_testnzc_pd (__m128d a, __m128d b)
int _mm256_testnzc_pd (__m256d a, __m256d b)
int _mm_testnzc_ps (__m128 a, __m128 b)
int _mm256_testnzc_ps (__m256 a, __m256 b)
int _mm_testnzc_si128 (__m128i a, __m128i b)
int _mm256_testnzc_si256 (__m256i a, __m256i b)
int _mm_testz_pd (__m128d a, __m128d b)
int _mm256_testz_pd (__m256d a, __m256d b)
int _mm_testz_ps (__m128 a, __m128 b)
int _mm256_testz_ps (__m256 a, __m256 b)
int _mm_testz_si128 (__m128i a, __m128i b)
int _mm256_testz_si256 (__m256i a, __m256i b)
