Support IfStmt to OpenQASM2 generation

Note: Aer can simulate conditional (bfunc) in the QObj and XACC translate IfStmt to bfunc appropriately.

Testing non-conventional gate set.

Signed-off-by: Thien Nguyen <nguyentm@ornl.gov>

The procedure was not properly taking into account non-IBM gateset, i.e., 2-q gates may not be CNOT.

Consider SWAPs in swap-shortest-path

Remove SWAP gates from the two-qubit gate whitelist for Staq placement
also modified in f1eedf04. Otherwise, Swap instructions between
non-adjacent qubits can slip through the swap-shortest-path
IRTransformation. An example of this would be the QCOR qft() routine,
which can generate a Swap between far-away qubits at the end.

Combined with f1eedf04

, fixes ORNL-QCI/qcor#199.

Creg can be larger than qreg (e.g., IQPE) and need to handle explicit Measure assignment.

IBM: Make bidirectional couplings when server sends no coupling_map

Signed-off-by: Alex McCaskey <mccaskeyaj@ornl.gov>

In the IBM backend, we require [x, y] to exist in the coupling map to
execute CX x,y -- [y, x] in the coupling map is not enough. So when IBM
does not include a coupling_map for a given backend, we need to include
both [i,j] and [j,i] for all qubits i,j s.t. i != j in the coupling map
we create; currently, we only include [i,j] for all qubits i,j with i <
j, which will cause errors if a circuit includes CX j,i.
