[Bug target/77633] AVX512: shuffle intrinsic has incorrect signature when optimizations are enabled

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77633 --- Comment #5 from Andrew Pinski --- I see clang does not implement this intrinsics this way. They accept int.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77633 --- Comment #4 from Wenzel Jakob --- Aha, interesting -- that breaks it: test.cpp(9): error: argument of type "int" is incompatible with parameter of type "_MM_PERM_ENUM={_MM_PERM_ENUM}"

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77633 --- Comment #3 from Jakub Jelinek --- Does it work even if you #define __INTEL_COMPILER_USE_INTRINSIC_PROTOTYPES 1 before including immintrin.h?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77633 --- Comment #2 from Wenzel Jakob --- I just tried compiling this snippet with ICC 17.0.0. It accepts it without warnings (-Wall -Wconversion -Wextra). So even if the signature is different, ICC seems to be more

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77633 --- Comment #1 from Jakub Jelinek --- Looking at ICC 16.0.2, it uses the same prototypes though, again with _MM_PERM_ENUM as the type of this argument. It is true the AVX512 manual states int rather than _MM_PERM_ENUM, so I don't know what is
