Bug type: crash
Component: SLPVectorizer
Bug location: llvm/lib/Transforms/Vectorize/SLPVectorizer.cpp: castToScalarTyElem
Issue title: A/F: `getNumElements(ScalarTy) < getNumElements(VecTy) && (getNumElements(VecTy) % getNumElements(ScalarTy) == 0)' failed after 1813ffd
Labels: llvm:SLPVectorizer
crash
Reported by: dyung

Several of our internal tests started hitting an assertion failure while building, one of which I bisected back to commit 1813ffd. Consider the following code:
```c++
typedef long long __m64 __attribute__((__vector_size__(8), __aligned__(8)));
static __inline__ long long foo(__m64 m) { return (long long) m; }
struct c {
  long a : 43;
  long b : 61;
} d;
void e() {
  volatile __m64 f;
  long g, i = d.b = g = foo(f);
  d.a = i;
}
```
When compiled with optimizations with a compiler that includes 1813ffd, it hits an assertion failure:
```

I don't know if it reproduces on an ARM targeting compiler, I used an x86-64 targeting x86-64 compiler. Also the compiler currently used by godbolt was built from commit f56cdd4a45b7bbe84be5d4ba9442eb7071605efc which does not include 1813ffd6b2eb04ee2c296a4399a18748740a439d which introduced the issue.

    [SLP][REVEC] Fix false assumption of the source for castToScalarTyElem. (#99424)
    
    The argument V may come from adjustExtracts, which is the vector operand
    of ExtractElementInst. In addition, it is not existed in getTreeEntry.
    
    The vector operand of ExtractElementInst may have a type of <1 x Ty>,
    ensuring that the number of elements in ScalarTy and VecTy are equal.
