David Green f2a92db29e [AArch64] Don't treat SVE scalable extends as free widening instructions 
The logic in isWideningInstruction handles instructions like uaddw and
smull, where 'add(x, zext(y))' or 'mul(sext(x), sext(y))' can be
converted to single instructions, making the extends free. This doesn't
apply the same to SVE instructions though.
https://godbolt.org/z/695d3nhGd

(There are instructions like SMULLT/B, but they require top/bottom lane
interleaving. That is similar to MVE instructions, which required a
special pass to perform the lane interleaving).

This patch just bails out of the call to isWideningInstruction if the
vector is scalable, getting a more accurate cost.
