Document in the context what happens with id overflow. (#2159)
Added documentation to the ir context to indicates that TakeNextId()
returns 0 when the max id is reached.  TODOs were added to each call
sight so that we know where we have to start to handle this case.

Handle id overflow in |SplitLoopHeader|.

Handle id overflow in |GetOrCreatePreHeaderBlock|.

Handle failure to create preheader in LICM.

use Pass::Run to set the context on each pass. (#1708)
Currently the IRContext is passed into the Pass::Process method. It is
then up to the individual pass to store the context into the context_
variable. This CL changes the Run method to store the context before
calling Process which no-longer receives the context as a parameter.

Move the ir namespace to opt. (#1680)
This CL moves the files in opt/ to consistenly be under the opt::
namespace. This frees up the ir:: namespace so it can be used to make a
shared ir represenation.
