PATCH: CALL_EXPR representation part 2/9 (builtins.c and fold-const.c)

[Sandra Loosemore]

Here's part 2 of the CALL_EXPR representation changes.  This is by far the
largest chunk, consisting of changes to builtins.c and fold-const.c.

See my part 0 message for a high-level overview of what has changed.
Additionally, when I submitted the patch for the original version of the changes
to the LTO branch, I was asked to make stylistic changes to consistently use
NULL_TREE or NULL_RTX (as appropriate) instead of constant 0 throughout
builtins.c.  So that's also contributed to making this patch extra-gigantic.  :-)
