Akira Hatanaka a22e4b71f4 [ARM] Define subtarget feature "reserve-r9", which is used to decide
whether register r9 should be reserved.

This change is needed because we cannot use a backend option to set
cl::opt "arm-reserve-r9" when doing LTO.

Out-of-tree projects currently using cl::opt option "-arm-reserve-r9" to
reserve r9 should make changes to add subtarget feature "reserve-r9" to
the IR.
