2de2319124 Fix PR4748: don't fold gep(bitcast(x)) into bitcast(gep) when x
is itself a bitcast.  Since we have gep(bitcast(bitcast(y))) in this
case, just wait for the two bitcasts to get zapped.  This prevents
instcombine from confusing some aliasing stuff, and allows it to
directly eliminate the load in the testcase.

7438106207 give instcombine a custom IRBuilder that adds new instructions to the
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.

c3a3e3682b rename AddUsesToWorkList -> AddOperandsToWorkList. The
former looks too much like AddUsersToWorkList and keeps

to do the same thing in a simpler way.

7a1e924b9a inline the trivial AddToWorkList/RemoveFromWorkList methods
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.

9b35a09e7e - Add target lowering methods to get the preferred format for the FDE and LSDA

  working for Darwin in 64-bit mode now.

cdfa01bf0f PR4795: Remove EEVT::isFP, isInt and isVec types used by TableGen's type
inferencing.  As far as I can tell, these are equivalent to the existing
MVT::fAny, iAny and vAny types, and having both of them makes it harder
to reason about and modify the type inferencing code.

The specific problem in PR4795 occurs when updating a vAny type to be fAny
or iAny, or vice versa.  Both iAny and fAny include vector types -- they
intersect with the set of types represented by vAny.  When merging them,
choose fAny/iAny to represent the intersection.  This is not perfect, since
fAny/iAny also include scalar types, but it is good enough for TableGen's
type inferencing.
