and that will make Caller too big to inline, see if it
might be better to inline Caller into its callers instead.
This situation is described in PR 2973, although I haven't
tried the specific case in SPASS.

to declare that they preserve other passes without needing to pull in
additional header file or library dependencies. Convert MachineFunctionPass
and CodeGenLICM to make use of this.

already on the worklist, and print Visited when an instruction is about to be
visited.  Net, on one input, this reduced the output size by at least 9x.

When MallocInst goes away this code will be subsumed as part of
calls and work just fine...

out of it, and jump threading, condprop and gvn are now getting
most of the benefit.  This was approved by Nicholas and Nicolas.

an i8* use getInt8PtrTy.

the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

This fixes PR5130.

Do away with the strange use of BitVectors in SSI, and just use normal sets.  This makes the code much more C++/LLVM-ish.

Similarly, it can be marked setPreservesAll, since it does no work in its runOnFunction.

The bitcast case is not needed here: instcombine turns icmp(bitcast(x), null) -> icmp(x, null) already.

These are important to push up to encourage jump threading.  This shrinks 176.gcc a bit.

simple constants for the true/false value of the select.  We now
do phi translation etc.  This really fixes PR4895 :)

that are phi nodes.  Also tighten up FoldOpIntoPhi to treat constantexpr
operands to phis just like other variables, avoiding moving constantexpr
computations around.
