Optimizing: Add debugging output for HInstruction.
Allow printing individual instruction and its arguments with
the HGraphVisualizer. Arguments are dumped "recursively"
(but implemented with a queue instead of actual recursion).
For example, printing the Return instruction from the method
Main.testLoop17 in 530-checker-lse yields
v28 Return [i27] dex_pc:23 loop:none
i27 Add [i24,i26] dex_pc:22 loop:none
i24 Phi [i5,i15] dex_pc:n/a reg:0 is_catch_phi:false loop:none
i5 IntConstant dex_pc:0 1 loop:none
i15 IntConstant dex_pc:5 2 loop:none
i26 InstanceFieldGet [l6] dex_pc:20 field_name:TestClass.i field_type:Int32 loop:none
l6 NullCheck [l1] dex_pc:1 env:[[i5,_,_,l1,i2]] loop:none
l1 ParameterValue dex_pc:n/a loop:none
Test: Manual; modify LSE to print the instruction above.
