    Consider the following code:
```c++
#include <immintrin.h>

__attribute__((target("avx512bw")))
static __attribute__((always_inline)) __m512i MM512_MASK_ADD_EPI8(__m512i src,
 __mmask64 k,
 __m512i a,
 __m512i b) {
    __asm__("vpaddb\t{%3, %2, %0 %{%1%}" : "+v"(src) : "Yk"(k), "v"(a), "v"(b));
    return src;
}

__attribute__((target("avx512bw")))
__m512i F(__m512i src, __mmask64 k, __m512i a, __m512i b) {
    return MM512_MASK_ADD_EPI8(src, k, a, b);
}

__attribute__((target("avx512bw,avx512dq")))
__m512i G(__m512i src, __mmask64 k, __m512i a, __m512i b) {
    return MM512_MASK_ADD_EPI8(src, k, a, b);
}

__attribute__((target("avx512bw,avx512vl")))
__m512i H(__m512i src, __mmask64 k, __m512i a, __m512i b) {
    return MM512_MASK_ADD_EPI8(src, k, a, b);
}
```
Functions `F`, `G`, and `H` are all inlined (as expected) when compiling with previous versions of clang (up to and including version 16). Testing with LLVM 17 RC yields a different result: only `F` is inlined and horrible code is generated for `G` and `H`. I believe this regression is caused by https://github.com/llvm/llvm-project/commit/d6f994acb3d545b80161e24ab742c9c69d4bbf33.

Please revert that change or apply the appropriate fix to `X86TargetTransformInfo.cpp` for the LLVM 17 release.
