Fix issue 18489 - SROA w/ vector arguments

Since we can't easily slice the contents of a XMM register avoid slicing
symbols passed in such registers.

More codegen bugs, cool.

Here's [1] the culprit, the problem is the following:
```
a is fastpar and using register XMM1
__a_8 is fastpar and using register NOREG
```

The latter _should_ be the second half of the `a' parameter, I don't know if
the NOREG is right here.
