  -----------
  [RISCV] Use getSignedConstant for negative values. (#125903)

The APInt constructor asserts if bits are set past the size of the APInt
unless it is signed. This currently fails on RV32 because more than XLen
bits are set.

(cherry picked from commit 0d7ee520d3a9b8997adf8eaaa22b33db9659d94e)
