dd71643cf1 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.

d53d314bd6 add a new InstCombineWorklist::AddValue method that works even 
if the operand is not an instruction.

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

13202514e1 rename AddUsesToWorkList -> AddOperandsToWorkList. The 
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.

bc61205626 llvm-mc: MCStreamer cleanups. - Remove EmitLocalSymbol, this is unsupported for now. 
- Switch Emit{CommonSymbol,Zerofill} to take alignment in bytes (for consistency).

1f8e8caacb 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.

df2191a33d default count-aa to -print-all. The whole reason to use count-aa is 
to see what queries are being made by a transformation, we might as well
default to printing them.

9dddea2ec3 - Add target lowering methods to get the preferred format for the FDE and LSDA 
encodings.
- Make some of the values emitted by the FDEs dependent upon the pointer
  size. This is in line with how GCC does things. And it has the benefit of
  working for Darwin in 64-bit mode now.

2cc9f2ac91 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.

9524ef5cfa install-sh chmods to 0755 by default, and this causes 'git diff' to show

only to 0644, these are not executable files after all!
