241dcacc04 Add a new constant manager class.
This patch adds a new constant manager class to interface with
analysis::Constant.  The new constant manager lives in ir::IRContext
together with the type manager (analysis::TypeManager).

The new analysis::ConstantManager is used by the spec constant folder
and the constant propagator (in progress).

Another cleanup introduced by this patch removes the ID management from
the fold spec constant pass, and ir::IRContext and moves it to
ir::Module. SSA IDs were maintained by IRContext and Module.  That's
pointless and leads to mismatch IDs. Fixed by moving all the bookkeeping
to ir::Module.

d2938e4842 Re-format files in source, source/opt, source/util, source/val and tools.
NFC. This just makes sure every file is formatted following the
formatting definition in .clang-format.

Re-formatted with:

$ clang-format -i $(find source tools include -name '*.cpp')
$ clang-format -i $(find source tools include -name '*.h')

476cae6f7d Add the IRContext (part 1)
This is the first part of adding the IRContext.  This class is meant to
hold the extra data that is build on top of the module that it
owns.

The first part will simply create the IRContext class and get it passed
to the passes in place of the module.  For now it does not have any
functionality of its own, but it acts more as a wrapper for the module.

The functions that I added to the IRContext are those that either
traverse the headers or add to them.  I did this because we may decide
to have other ways of dealing with these sections (for example adding a
type pool, or use the decoration manager).

I also added the function that add to the header because the IRContext
needs to know when an instruction is added to update other data
structures appropriately.

Note that there is still lots of work that needs to be done.  There are
still many places that change the module, and do not inform the context.
That will be the next step.

1040a95b3f Re-factor Phi insertion code out of LocalMultiStoreElimPass
Including a re-factor of common behaviour into class Pass:

The following functions are now in class Pass:

- IsLoopHeader.
- ComputeStructuredOrder
- ComputeStructuredSuccessors (annoyingly, I could not re-factor all
  instances of this function, the copy in common_uniform_elim_pass.cpp
  is slightly different and fails with the common implementation).
- GetPointeeTypeId
- TakeNextId
- FinalizeNextId
- MergeBlockIdIfAny

This is a NFC (non-functional change)

1e309af80a Added --compact-ids to /tools/opt
The pass remaps ids to a compact set which starts with %1 and
has no gaps.
