  cg: move get_member() to dt_cg.c

It will be used by both dt_prov_ip.c and dt_prov_tcp.c.  Updated the
dt_cg_ctf_offsetof() function to provide the load/store operand size
if needed sp that the new dt_cg_tramp_get_member() can use that rather
doing its own type lookup, etc.

Updated all uses of dt_cg_ctf_offsetof() and dt_cg_tramp_get_member().

  cg: validate tstring alloc/free

Rather than indiscriminately resetting tstring allocations at the
beginning of a compilation, actually verify that alloc/free of
tstrings is done correctly, i.e. that none are left allocated after
compilation is done.

  cg: optimize ternary expressions for strings

If either side of a ternary expression has a tstring value, it can be
re-used to store the value of the ternary expression, reducing the
need for tstring allocation, especially in nested ternaries.
