<pre>Assembler expects that carry-in and carry-out operands are registers. However
when a constant is specified, it breaks assembler.
Assembler should be corrected to detect these cases and issue a meaningful
error message.
Examples of failed tests:
// VI
v_addc_u32 v1, -1, v2, v3, vcc
v_addc_u32 v1, vcc, v2, v3, 0
// GFX10, ws=32
v_add_co_ci_u32_e64 v5, 0, v1, v2, s1
v_add_co_ci_u32_e64 v5, s0, v1, v2, 1</pre>
