Bump up MAX_SUBTARGET_FEATURES
Bump up MAX_SUBTARGET_FEATURES

Summary:
Currently, ARMGenSubtargetInfo (from ARM.td) is reaching the limit of 96:
  enum : uint64_t {
       ...
       XScale = 95
  };
       
We need to bump the maximum value up to accommodate future changes and/or customized subtarget definitions.
