Duncan P. N. Exon Smith 78c0b35bf7 IR: Rewrite ConstantUniqueMap 
Rewrite `ConstantUniqueMap` to be more similar to
`ConstantAggrUniqueMap`.

  - Use a `DenseMap` with custom MapInfo instead of a `std::map` with
    linear lookups and deletion.
  - Don't waste memory explicitly storing (heavyweight) keys.

Only `ConstantExpr` and `InlineAsm` actually use this data structure, so
I also updated them to use it.

This code cleanup is a precursor to reducing RAUW traffic on
`ConstantExpr` -- I felt badly adding a new (linear) call to
`ConstantUniqueMap::FindExistingKey`, so this designs away the concern.

A follow-up commit will transition the users of `ConstantAggrUniqueMap`
over.

Low Level Virtual Machine (LLVM)
================================

This directory and its subdirectories contain source code for the Low Level
Virtual Machine, a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

LLVM is open source software. You may freely distribute it under the terms of
the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you're writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
