substituted operands.  For this testcase:

int %test(int %A, int %B) {
  %C = call int asm "xyz $0, $1, $2", "=r,r,r"(int %A, int %B)
  ret int %C
}

we now emit:

_test:
        or r2, r3, r3
        or r3, r4, r4
        xyz r2, r2, r3  ;; look here
        or r3, r2, r2
        blr

... note the substituted operands. :)

- Added a new format for instructions where the source register is implied
  and it is same as the destination register. Used for pseudo instructions
  that clear the destination register.
