  cg: allow input to translator to be NULL

Some translators support NULL as input pointer value.  The code generator
was performing a NULL-check on a the LHS of a PTR or DOT node before
considering the possibility that the node is subject to translator
handling.  The check should happen after translator handling.

With this patch, tst.ProcModelTrans.d works but only for the case of
NULL input.  The test is changed to actually use a real task_struct as
input.  New test tst.NullInput.d exercises the case this patch fixes.

  Log Message:
  -----------
  cg: correct bitfield offset determination

The C compiler (together with binutils) can represent bitfields using
one of two representations: store the actual offset of the bitfield in
ctm_offset, or store the base offset of the underlying type in ctm_offset
and store the offset within the underlying type as cte_offset.

  cg: fix tstring leak in translator members that yield string values

When a translator member yields a string value, the tstring holding the
value was not properly tracked.  This resulted in an assertion failure
in test/demo/ip/ipproto.d.
