  Log Message:
  -----------
  [RISCV] Don't construct a subtarget for function declarations in RISCVPromoteConstant. (#224115)

Intrinsic declarations in particular don't have a target-features
attribute so the subtarget constructor may print warning like:

hard-float 'd' ABI can't be used for a target that doesn't support the D
instruction set extension

This can occur in LTO builds in -mcpu is not passed to the clang driver
on the LTO step. The target-machine won't have any CPU features.
