d6c067630d Handle extract with no index in VDCE. (#2305)
It is legal, but not generated by any SPIR-V producer: an OpCompositeExtract
with no indexes.  This is essentially just a copy of the object, so we
treat them that way.  We simply propagate the live variables of the
result to the operand.

Fixes https://crbug.com/919181.

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.

Vector DCE (#1512)
Introduce a pass that does a DCE type analysis for vector elements
instead of the whole vector as a single element.

It will then rewrite instructions that are not used with something else.
For example, an instruction whose value are not used, even though it is
referenced, is replaced with an OpUndef.
