and testing is easier.  A good example is the unknown-location.ll test that
now can just look for ".loc 1 0 0".  We also don't use a DW_LNE_set_address for
every address change anymore.

Some of these maps may merge in the future, but for now it's convenient to have

It is generally not sufficient to check if the starting offset is in range
of the maximum offset that can be efficiently used for the target.

This makes it more clear that the symbol is an internal, compiler-generated
name and gives a little more description about its contents.

It was mistakenly looking at the pointer type when checking for the size of

Change the existing checking method to a more direct one:
rather than seeing if all predecessors belong to the loop,
check that the replacing value is either not in any loop or
is in a loop that contains the phi node.
