  [AsmPrinter] add optimisation remark for target-features (#222074)

In clang we have `--print-enabled-extensions` which will print the
AArch64 extensions enabled for a given TU. However, sometimes it is
useful to be able to print out the actual subtarget features for each
function, for debugging/testing purposes. Add an optimisation remark for
that.
