* Validate version 5 of clspv reflection
* Add validation for instructions in versions 2 through 5
* Change the instruction reported for remaining indices on an access
chain to the access chain itself for clarity
* update spirv-headers
* Fix layout validation
Fixes#5010
* Unless scalar block layout is enabled, no member can reside at an
offset between the end of the previous member that is a struct or
array and the next multiple of that alignment
* Remove a dead if that was introduced

open_quote value becomes npos when it fails to find '\'' and then is used to
compute the string length for writing to result. This causes crash in win32 builds of the test.

* Only validate full layout in a vulkan environment
* Universal validation still checks that the right decorations are
present, but the values are only considered for vulkan
* One exception is that invalid overlaps are only checked for vulkan
* This is a pragmatic choice as SPIR-V doesn't define the size of
types so the amount of universal checking would be quite limited
* Removed redundant check for GLSLShared and GLSLPacked decorations
* Should never have been validated as part of universal validation
* make conditionals independent

* Assign a reflexive dominator if no other dominator can be found using
forward traversals
* This prevents a null dereference of a pointer in the sorting of the
output
The always-friendly messages make it harder to debug when the
disassembly is later generated without friendly names.
Additionally, the friendly-name-mapper is slow. Disabling it improves
performance of an ANGLE test that creates numerous shaders by ~5%.
Half the messages used to output 'id[%name]' and half id[%name]. With
this change, all messages consistently output 'id[%name]'. Some typos
are also fixed in the process.

* Adds structural reachability to basic blocks
* calculated in same manner as reachability, but using structural
successors
* Change structured CFG validation to use structural reachability
instead of reachability
* Fix some invalid reducer cases
* Structural dominance introduced in SPIR-V 1.6 rev2
* Changes the structured cfg validation to use structural dominance
* structural dominance is based on a cfg where merge and continue
declarations are counted as graph edges
* Basic blocks now track structural predecessors and structural
successors
* Add validation for entry into a loop
* Fixed an issue with inlining a single block loop
* The continue target needs to be moved to the latch block
* Simplify the calculation of structured exits
* no longer requires block depth
* Update many invalid tests
