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.
