Make the constant and type manager analyses. (#2250)
Currently it is impossible to invalidate the constnat and type manager.
However, the compact ids pass changes the ids for the types and
constants, which makes them invalid.  This change will make them
analyses that have to been explicitly marked as preserved by passes.
This will allow compact ids to invalidate them.

Fixes #2220.

Cleanup includes. (#1795)
This Cl cleans up the include paths to be relative to the top level
directory. Various include-what-you-use fixes have been added.

Cleanup extraneous namespace qualifies in source/opt. (#1716)
This CL follows up on the opt namespacing CLs by removing the
unnecessary opt:: and opt::analysis:: namespace prefixes.

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.

a1f9e1342e Preserve inst-to-block and def-use in passes.
The following passes are updated to preserve the inst-to-block and
def-use analysies:

	private-to-local
	aggressive dead-code elimination
	dead branch elimination
	local-single-block elimination
	local-single-store elimination
	reduce load size
	compact ids (inst-to-block only)
	merge block
	dead-insert elimination
	ccp

The one execption is that compact ids still kills the def-use manager.
This is because it changes so many ids it is faster to kill and rebuild.

Does everything in
https://github.com/KhronosGroup/SPIRV-Tools/issues/1593 except for the
changes to merge return.

0e9f2f948a Add id to name map
Adding a map from an id to it set of OpName and OpMemberName
instructions.  This will be used in KillNameAndDecorates to kill the
names for the ids that are being removed.

In my test, the compile time for 50 shaders went from 1m57s to 55s.
This was on linux using the release build.

Fixes #1290.

b86eb6842b Convert private variables to function scope.
When a private variable is used in a single function, it can be
converted to a function scope variable in that function.  This adds a
pass that does that.  The pass can be enabled using the option
`--private-to-local`.

This transformation allows other transformations to act on these
variables.

Also moved `FindPointerToType` from the inline class to the type manager.
