Avoid use of 'sanity' and 'sanity check' in the code base (#3585)
In line with:

  https://source.android.com/setup/contribute/respectful-code

this change uses the terms 'coherence' and 'coherence check' where
'sanity' and 'sanity check' were previously used.

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.

Part of https://github.com/KhronosGroup/SPIRV-Tools/issues/1841.

1e9fc1aac1 Add base and core bindless validation instrumentation classes (#2014)
* Add base and core bindless validation instrumentation classes

* Fix formatting.

* Few more formatting fixes

* Fix build failure

* More build fixes

* Need to call non-const functions in order.

Specifically, these are functions which call TakeNextId(). These need to
be called in a specific order to guarantee that tests which do exact
compares will work across all platforms. c++ pretty much does not
guarantee order of evaluation of operands, so any such functions need to
be called separately in individual statements to guarantee order.

* More ordering.

* And more ordering.

* And more formatting.

* Attempt to fix NDK build

* Another attempt to address NDK build problem.

* One more attempt at NDK build failure

* Add instrument.hpp to BUILD.gn

* Some name improvement in instrument.hpp

* Change all types in instrument.hpp to int.

* Improve documentation in instrument.hpp

* Format fixes

* Comment clean up in instrument.hpp

* imageInst -> image_inst

* Fix GetLabel() issue.

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.

10e5d7cf13 Add a loop peeling pass.
For each loop in a function, the pass walks the loops from inner to outer most loop
and tries to peel loop for which a certain amount of iteration can be done before or after the loop.

To limit code growth, peeling will not happen if the growth in code size goes above a configurable threshold.

bdf421cf40 Add loop peeling utility
The loop peeler util takes a loop as input and create a new one before.
The iterator of the duplicated loop then set to accommodate the number
of iteration required for the peeling.

The loop peeling pass that decided to do the peeling and profitability
analysis is left for a follow-up PR.
