return RBlock.  Otherwise we'll incorrectly return NULL.

Also relax an assertion in VisitWhileStmt(). Reset 'Block' when it is finished.

After a recent fix to not set the default architecture to "x86_64", the string value for the default arch was coming out as a value that shouldn't be user visible. Now we don't show any value when it isn't set.

This doesn't prevent us from inserting a loop preheader later on, if that is

Critical edges going into a loop are not as bad as critical exits. We can handle
them by splitting the critical edge, or by having both inside and outside
registers live out of the predecessor.

Example:

bb0:
  x = 1
bb1:
  use(x)
  ...
  x = 2
  jump bb1

When x is isolated in bb1, the inner part breaks into two components, x1 and x2:

bb0:
  x0 = 1
bb1:
  x1 = x0
  use(x1)
  ...
  x2 = 2
  x0 = x2
