workslist and is set to insert new instructions before the current one.
Convert a bunch of stuff that used to call InsertNewInstBefore over to
use it, greatly simplifying code and making it more natural.

There is still a lot more to go, but this is a good start.

Simplify most uses of AddOperandsToWorkList to use AddValue and
inline it into the one remaining callsite.

argument stronger typed.

former looks too much like AddUsersToWorkList and keeps
confusing me.

Remove AddSoonDeadInstToWorklist and change its two callers
to do the same thing in a simpler way.

into their callers.  simplify ReplaceInstUsesWith.  Make
EraseInstFromFunction only add operands to the worklist if
there aren't too many of them (this was a scalability win
for crazy programs that was only infrequently enforced).
Switch more code to using EraseInstFromFunction instead of
duplicating it inline.  Change some fcmp/icmp optimizations
to modify fcmp/icmp in place instead of creating a new one
and deleting the old one just to change the predicate.

Improve diagnostics for missing members. This renames the err_typecheck_no_member to err_typecheck_no_member_deprecated. The idea is that err_typecheck_no_member_deprecated should be phased out and any call sites that reference it should call DiagnoseMissingMember instead.

The change in lib/AST/DeclCXX.cpp is mostly a large reindentation; I 
couldn't figure out a good way to avoid it.
