This patch adds support for the `ud ui5` macro instruction. The `ui5` operand must be inthe range `0-31`. The macro expands to: `amswap.w $rd, $r1, $rj` where `ui5` specifies the register number used for `$rd` in the expanded instruction, and `$rd` is the same as `$rj`. Relevant binutils patch: https://sourceware.org/pipermail/binutils/2025-December/146042.html
