Add two new classes: WeakVH and AssertingVH. These are both "ValueHandles",
...
which are effectively smart pointers to Value*'s. They are both very light
weight and simple, and react to values being destroyed or being RAUW'd.
WeakVN does a best effort to follow a value around, including through RAUW
operations and will get nulled out of the value is destroyed. This is useful
for the eventual "metadata that references a value" work, because it is a
reference to a value that does not show up on its use_* list.
AssertingVH is a pointer that compiles down to a dumb raw pointer when
assertions are disabled. When enabled, it emits an assertion if the
pointed-to value is destroyed while it is still being referenced. This
is very useful for Maps and other things, and should have caught the recent
bugs in CallGraph and Reassociate, for example.

preprocessor, if at all possible.

Throttle back "fold select into operand" transformation. InstCombine should not generate selects of two constants unless they are selects of 0 and 1.
...
e.g.
define i32 @t1(i32 %c, i32 %x) nounwind {
%t1 = icmp eq i32 %c, 0
%t2 = lshr i32 %x, 18
%t3 = select i1 %t1, i32 %t2, i32 %x
ret i32 %t3
}
was turned into
define i32 @t2(i32 %c, i32 %x) nounwind {
%t1 = icmp eq i32 %c, 0
%t2 = select i1 %t1, i32 18, i32 0
%t3 = lshr i32 %x, %t2
ret i32 %t3
}
For most targets, that means materializing two constants and then a select. e.g. On x86-64
movl %esi, %eax
shrl $18, %eax
testl %edi, %edi
cmovne %esi, %eax
ret
=>
xorl %eax, %eax
testl %edi, %edi
movl $18, %ecx
cmovne %eax, %ecx
movl %esi, %eax
shrl %cl, %eax
ret
Also, the optimizer and codegen can reason about shl / and / add, etc. by a constant. This optimization will hinder optimizations using ComputeMaskedBits.
