clean: constexpr-ify and unify anon namespace use (#4991)
Constexpr guaranteed no runtime init in addition to const semantics.
Moving all opt/ to constexpr.
Moving all compile-unit statics to anonymous namespaces to uniformize
the method used (anonymous namespace vs static has the same behavior
here AFAIK).

Switch SPIRV-Tools to use spirv.hpp11 internally (#4981)
Fixes #4960

* Switches to using enum classes with an underlying type to avoid
  undefined behaviour

Handle out-of-bounds accesses in VDCE (#4518)
It is possible that other optimization will propagate
a value into an OpCompositeExtract or OpVectorShuffle
instruction that is larger than the vector size.
Vector DCE has to be able to handle it.

Fixes https://github.com/KhronosGroup/SPIRV-Tools/issues/4513.

Preserve debug info in vector DCE pass (#3497)
This commit lets the vector DCE pass preserve the OpenCL.DebugInfo.100
information properly. When the vector DCE pass determines the liveness
of instructions, the debug instructions must not affect the decision. In
addition, when it kills some instructions, it has to kill DebugValue
instructions that use the killed instructions. When it updates some
composite values to meaningful values (not undef), it has to remove
DebugValue because the value information becomes incorrect.

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.

Handle CompositeInsert with no indices in VDCE (#2258)
* Handle CompositeInsert with no indices in VDCE

In the spec, there it nothing that forces an OpCompositeInsert to have
an index, but VDCE assumes there is at least 1 in a couple places.

This commit updates VDCE to handle these cases.

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.
