  Log Message:
  -----------
  [X86] LowerAsmOperandForConstraint - ensure we treat L constraint immediates as signed constants (#171098)

getTargetConstant no longer tolerates sign-extended values that can't be
represented by the appropriate APInt bitwidth, which defaults to
unsigned behaviour.

Fixes #166058
