a value from the worklist required scanning the entire worklist to remove all
entries.  We now use a combination map+vector to prevent duplicates from
happening and prevent the scan.  This speeds up instcombine on a large file
from the llvm-gcc bootstrap from 189.7s to 4.84s in a debug build and from
5.04s to 1.37s in a release build.

This caused a warning for construction with -1. Avoid the warning by using

Adjust to changes in ConstantRange interface.

llvm-svn: 34762

Remove ConstantInt from ConstantRange interface and adjust its users to
compensate.

llvm-svn: 34758

First round of ConstantRange changes. This makes all CR constructors use
only APInt and not use ConstantInt. Clients are adjusted accordingly.

Change use of "packed" term to "vector" in comments, strings, variable
names, etc.

Rename PackedType -> VectorType, ConstantPacked -> ConstantVector, and
PackedTyID -> VectorTyID. No functional changes.
