This reverts https://github.com/llvm/llvm-project/pull/132976. The PR incorrectly claimed that this makes inlining more liberal, referencing the string comparison in TargetTransformInfoImpl.h. However, the implementation that actually applies is the one in BasicTTIImpl.h, which performs a feature subset comparison. As such, this regressed inlining, most concerningly of functions without +vector into functions with +vector. Revert the change to restore the previous behavior.
